Builders employ a wide range of methods to keep their foundation safe. Experienced construction designers know that a dry foundation is necessary for creating a building that will be problem-free for generations.

There are lots of ways to achieve the goal of keeping your foundation dry. A rare but effective method of building a foundation that also helps keep it dry in certain soils is to create a raft foundation.

When should you choose a raft foundation

A raft foundation is not always the best foundation choice. Under most normal soil conditions, a regular poured foundation will be suitable for construction of even the tallest building.

If, however, you are building on weak soil that might give way under the full weight of your building, a raft foundation is the right answer.

It works in these conditions because the raft foundation is one large, flat surface on which you place the entire building. The flat, open surface of the “raft” or mat works to distribute the weight over the entire surface of the foundation. By doing this, the weight on any one given spot is reduced.

By distributing this weight evenly, no one spot carries a great weight. Instead, the building weight is distributed and thus it is less prone to shift, drop, or settle.

What is a raft foundation, exactly?

The raft foundation works as the name implies. Think of a raft of the sort you might use to escape from a desert island. It is a flat surface upon which everything else is built.

It is not like a building constructed on pilings, footings or columns of wood or concrete which only make contact on certain points of the surface below.

The flat surface is its own full surface to build on, but not to drill through or otherwise breach.

It lays on the excavated flat surface at the base of the building site. Once it is waterproofed and poured into place, everything else is constructed on top of it.

A raft foundation doesn’t float, and for this reason it’s best to think of it as a mat foundation, in that it lays there, and everything else happens on top of it.

A raft foundation is not necessarily used for the purpose of waterproofing, though it also comes up in waterproofing conversations. The point of choosing this foundation type is to create the safest, most secure foundation on loose soil.

There is no doubt that this era of COVID and quarantine has raised the bar for the expectation of employee safety. Where previously employers had a responsibility to keep their workers safe from those on-site dangers that could be seen and anticipated, suddenly they had a new enemy.

Our employees and our productivity are now threatened by viruses that are invisible and can be passed before the carrier shows symptoms.

It is more important than ever to invest in employees’ safety from contagious diseases, and to find reliable providers of the PPE (personal protective equipment) they need to get safely through the day.

Keep employees safe from airborne COVID-19

Many companies found themselves in a competition for PPE when the quarantine started and the virus challenged our productivity and supply lines. Mar-Flex now has a range of options for protecting your employees with their new PPE offerings.

Mar-Flex offers a full range of personal protective equipment to keep your employees safe during COVID-19 and in other similar situations.

First, Mar-Flex offers masks, in order to protect employees and customers from airborne particles. In addition to stopping COVID, these masks have been shown to reduce the transmission of the flu and colds, meaning that investing in masks will help overall attendance and productivity.

A variety of designs are available, so employees can demonstrate personality while protecting everyone at the site.

In some situations, employees might risk contact with water droplets from infected people. In those cases, face shields are the necessary equipment. These keep employees safe from the spread of communicable diseases while allowing them to talk freely. Where masks might slip off during conversations, face shields remain in place.

Ensure safety with other PPE

Of course, airborne droplets are not the only concern we have for our employees and customers. We additionally need to protect them from surface contact with COVID and other communicable viruses.

For a variety of applications, Mar-Flex offers gloves. These can be used when your employees need to touch materials that might cause skin irritation, but where your employees still need the full function of their fingers for detail work.

These gloves are also handy for people who work with mail or other materials that come from an unknown source. Multiple contaminants might show up on envelopes and other external items, so surgical style gloves offer a level of safety and security.

Helping your employees feel safe is part of the optimal experience that keeps workers safe and feeling valued.

Finally, for every potential application, they offer hand sanitizer for office or construction site usage. Your employees and your guests will benefit from an abundance of hand sanitizer on countertops and in other common spaces.

Hand sanitizer remains an important part of your defense against the spread of communicable disease in your worksite.

Be prepared this winter and spring so your employees stay safe and productive.

Waterproofing a concrete foundation is a job best left to professionals, or to be attempted only by the most confident and accomplished do-it-yourselfer.

If you are in this second category, this guide can help you understand what you are up against and make the decision to do it or to hire the work out to a company like Mar-Flex.

Waterproofing or Dampproofing?

First you must understand whether the work you are doing is waterproofing or damp proofing.

• Will there be a great deal of exterior  ground pressure on the outside of the foundation and/or is the foundation submerged below ground?
• Is the space on the interior side of the wall to be used, either for storage or habitation / work?

If the answers to these questions are “yes”, then you are waterproofing, and your work is more rigorous than merely dampproofing.

Waterproofing Process

First, full expose as much of the external foundation as you can. This is easiest with new construction, of course, but even with an established building, care must be taken to reach the whole concrete side of the structure.

Then, patch any holes, chips or cracks with a commercial-grade mastic or cement patching mix.

Once that dries, clear the surface of any dirt or debris.

When the surface is dry and clean, treat it fully with a commercial grade waterproofing sealant. Be sure to wear appropriate protection for this process, including an appropriate mask to prevent breathing fumes.

When this surface dries a final time, apply an external waterproofing barrier. This final barrier might look like fabric, but it should be a product similar to GeoMat or ShockWave. These specially-made barriers are constructed to direct water away from the foundation of your home.

Once this is properly installed and inspected, begin the careful backfill of rock and soil around your home. Fill until you reach the level of your rainwater management system.

At the appropriate level, install a below-ground drainage system. This can be as simple as a french drain that will help capture water below the surface and direct it into your rainwater system and safely away from your home.

Enjoying your dry space !

Waterproofing the exterior of your home can last a lifetime. In fact, some Mar-flex products have guarantees that stretch as long as a lifetime when verified as being properly installed by a Mar-flex approved applicator on a residential application.

Some things change, and in 2020 that seems more true than ever.

One thing that hasn’t changed is the need to keep your basement dry. While you can always clean up after flooding and drainage issues, it is far better to avoid them in the first place.

But as a homeowner you will want to anticipate those costs to better budget your money and your time, and place a value on the investments you have made.

Using the general guidelines below will help you make the right choice for your situation.

Residential basement waterproofing costs vary by region. For this article we have referenced averages in the Cincinnati metro area and the Mason suburban region, for people in southwest Ohio looking for this information.

Individual situations will vary, of course, based on a variety of factors including the cause of the water infiltration, the setting of the house, the condition of the foundation, and more.

General Costs of Basement Waterfproofing in Cincinnati

Full basement waterproofing in Cincinnati averages $7,518. The typical range for this work falls between $4,000 and $12,000 with some projects costing nearly $20,000.

Of course there are lots of options here, including how completely watersealed the final work is. The full treatment can include digging out around the outside of the foundation, laying external waterproofing membranes, filling cracks, backfilling, drains and more.

A less comprehensive solution, perhaps one focusing on individual cracks and internal waterproof or moisture-proof paint will of course be cheaper by a magnitude.

General Costs of Basement Waterfproofing in Lebanon, Ohio

Even as far north as Lebanon, these same average costs hold up. It can be helpful to think of the projects in terms of the square footage.

Full waterproofing can average out to between $5 and $10 per square foot of your basement. If this is cost-prohibitive there is one acceptable alternative.

Perhaps your problem is more about moisture than water. In that case, you can hire someone to take a range of moisture-proofing steps that will economize, eventually costing between $3 and $6 per square foot.

Of course, you need to match the solution to your situation. If you’re finding standing water, a reputable company will not let you merely moisture-proof your basement. It would be a waste of time, and they would be back after the next major water event to make larger repairs.

When talking about moisture, mold, and all the problems that come with a wet basement, it is important to match the solution to the problem.

As always, Mar-Flex solutions are available to help you find the right solution for your southwest Ohio basement.

One of a homeowner’s top fears is water or moisture in their basement.

In some cases this can mean a messy, expensive, and time-consuming repair. The most comprehensive solutions involve the exterior of the house, trench-digging, and days of ugliness and inconvenience until the problem is solved.

Fortunately that isn’t always the case.

 Sometimes the problem is one that the homeowner can solve alone.

DIY Waterproof Sealer

There are many quality waterproof sealers on the market.

A quick search at Home Depot yields the following:

And a similar search at Lowe’s:

So you see there are a range of solutions.

Having heard of a product means that the company has a decent advertising budget. This does NOT mean the product is better, necessarily. 

In general, the process works the same whichever product you buy, and will be effective for roughly the same amount of time.

Be sure to read the labels to determine whether your project is a good match with the product. For instance, you likely want a product that blocks moisture and not something that focuses on blocking mold production.

Doing the Work

The project generally involves the following steps.

Purchase the necessary equipment including brushes, rollers, painters tape, mask, and sealant.

Prepare the surface by wiping off loose dust and small debris with a wet cloth. Allow to dry.

Prepare the environment by ventilating as much as possible.

Apply one or two coats of sealant according to the directions on the product.

It is possible to work in sections. If you are working around visible cracks, it is recommended to treat that as one section, so the crack gets an even coat (or two) of sealant. Then areas around the visible cracks can be sealed at a separate time as necessary.

Cleaning Up

Use mineral spirits or other recommended thinners to clean your brushes. Dispose of roller pads or clean them as you prefer.

Remove tape while the sealant is tacky but not wet. This allows you to pull the tape up without creating a runny mess, but also prevents the tape from becoming a permanent part of the finished project.

Wait the recommended period of time before returning furniture or storage units to the space. The presence of a strong odor even after the recommended drying time is a clue to wait even longer. Your application thickness, the humidity, and the level of ventilation all can cause drying times to vary from the directions. It is best to make sure it is fully dry rather than rush something back into place and damage the finish.

Who can do this DIY waterproofing project?

If your moisture problems are minor, this is an easy project you can do if you have ever painted a room. Even inexperienced DIYers should be able to accomplish this.

However, if the task seems too big, or you’re not sure this will stop the water, it is better to call the experts at Mar-Flex Waterproofing to get an estimate and a guarantee that the water will be stopped.

The most important part of any building is its foundation. and the greatest enemy of any foundation is water.

Thus, waterproofing, and finding the right materials to quickly and effectively waterproof the foundation of a building, is an integral part of every building project.

At Mar-Flex we believe ShockWave drainage insulation board is the fastest, and most cost-effective way to permanently waterproof the foundation of your next building project.

What is drainage insulation board?

When we were children, our parents helped us pull on rubber boots over our shoes so we could play in puddles. This allowed us to keep our feet dry while interacting with and even standing in puddles we would otherwise avoid.

In an ideal world, we could drop the foundation of a building into a pair of galoshes and be done with it. We could move forward knowing the project was permanently waterproofed. However, buildings are different from legs and feet, for all the obvious reasons.

Much of the concrete base of a foundation directly touches the ground. And a big portion of the walls of the foundation are underground. This means direct contact with dirt and water can’t be avoided.

Drainage insulation board is something like a pair of galoshes. This insulation board is attached to the exterior walls of your foundation project. When installed correctly, it covers the entire underground sidewall.

The material in the board must include important improvements to make it better for your foundation. Because it is the material standing between your foundation and the ground outside, it must withstand pressure from earth and water.

What does ShockWave drainage insulation board do that is different?

Made from reclaimed automotive polyethylene foam, ShockWave drainage insulation board is constructed to do more than merely keep water away from your foundation.

Ordinary rubber galoshes would allow water to pool and remain against the foundation of your building. This actually creates unnatural and structurally unsound pooling that could eventually cause your foundation to shift or your landscape to slide and collapse.

ShockWave, on the other hand, allows water to drain through the material down to tile drains. This natural, guided flow of water maintains the solid substrate around your foundation, keeping your building secure for generations.

Best yet, ShockWave is easy to install in combination with a waterproof membrane using adhesive or concrete nails.

You can find ShockWave drainage insulation board at Mar-Flex

In researching the best waterproofing materials for your building purposes, you likely have come across the term “polyethylene foam” and wondered what exactly it is.

Polyethylene foam, or PE, is a common material in a wide variety of waterproofing and other building applications. Because of its unique structure and ease of production, it can be shaped, molded, or layered for tasks in nearly every construction structure imaginable.

Qualities of polyethylene foam

PE foam’s qualities make it ideal for many applications.

First, it absorbs sound. This makes it effective as an insulator where sound suppression is important. While there are other substances that help prevent noise bleed in cars and construction, few are this inexpensive to manufacture.

Second, it is lightweight. This feature is why you will see PE used in many places in cars. As manufacturers seek to shave ounces off the weight of cars to hit CAFE (fuel efficiency) standards, designers turn to PE for insulation and vibration dampening. The weight does not matter as much in construction, where decision-making seldom balances on this measure, but it matters for transporting materials to the site.

Additionally, PE Is easy to make and shape. Manufacturers can shape it to an almost unlimited amount of widths and thicknesses, and even shape it to fit very specific contours. This  includes shapes with odd angles or rounded sides. This level of flexibility makes it an easy choice for designers.

Finally, PE resists tearing. This reduces the amount of accidental breaches and flaws that might compromise a construction project.

Why PE is great for building and waterproofing

Polyethylene foam has additional properties that make an excellent for building.

When you work with PE, even if you have to cut and shape it, it is does not create dust. This means you don’t have  to use the same level of safety equipment that you might with other forms of insulation or soundproofing.

Furthermore, PE resists all sorts of hazards often related to water. Mold, mildew,  and other bacterial nuisances won’t form on polyethylene foam. The ability to prevent mold and mildew is a major safety consideration for building indications.

Finally, though this is more rarely a concern at construction sites, PE resists chemicals and grease. Many forms of plastic are actually eaten or weakened by many common chemicals.  by being resistant to this sort of degradation, polyethylene foam proves to be a durable and reliable construction material.

Once upon a time, consumers expected that everything they purchased was made close to them or certainly in the same country.

Today, however, this has changed.

International trade, inexpensive foreign labor, and varying levels of technical knowledge means that any product we buy might have been made almost anywhere in the world. Quite frequently when we buy a large item such as a car, it is an amalgam of American and foreign parts and processes.

 However it still remains important to buy products made in the USA.

What does this label mean?

When a product says it was made in the USA, the company has proven to the Federal Trade Commission that “all or most all” of the product was, in fact, made in the United States.

Because the Federal Trade Commission cannot go around verifying every claim oh, they depend on a standard called “reasonable basis.” That is, the manufacturer must be able to make a “reasonable” claim and provide an explanation that seems to fit with being made entirely in the United States of American.

There is not technically a percentage of the content in an item that must be manufactured in the United States. Instead, the companies that make that claim should be able to show reasonable evidence that the majority of that item was made in the United States.

Why does it matter?

Being made in the United States matters a great deal. It is a guarantee then that your money is returning to the American economy and supporting American workers, some of whom live in your community.

Many patriots take pride in making sure that their dollars continue to support the American economy and their community, and that the taxes each sale generates also supports their local police, fire, and other services.

It is meaningful to many people that not just American executives get paid, but that our dollars go to support strong union labor, high paying jobs, and quality workmanship. And to know that this same money will be, in turn, invested in our own American companies and jobs.

It is part of a virtuous circle of the American economy.
