Waterproofing Foundation – Guidelines

If you’re building a new house, be sure the foundation is watertight so you don’t end up with a damp basement in a few years.Do you want to learn more? Visit  membranes

There are so many different waterproofing materials and methods on the market that it’s easy to get overwhelmed. So, what are your choices?

To help you decide, here’s a quick rundown of the most popular foundation waterproofing systems:

  1. Liquid rubber waterproofing membranes for foundations

Elastomeric polymerized coatings are composed of liquid rubber, the same high-quality substance used in automobile tyres.

They are simple to apply, dry quickly, and may be applied cold. You can do it yourself with the use of a sprayer, roller, or trowel. As the structure settles, the liquid dries into an elastic rubber covering capable of filling existing tiny holes and bridging any future fractures in the foundation wall. Rubber is a malleable material. They also typically come with a lengthy guarantee, and many of them are solvent-free or have minimal solvent content. Very cost-effective.

  1. Liquid Rubber Foundation waterproofing product, hot applied:

It’s a rubberized asphalt mix that creates a monolithic waterproofing membrane that’s both robust and flexible. It may also be used on roofs.

Benefits: Adheres to almost any structural surface. Ideal for uneven, rough surfaces. Watertight, monolithic, seam-free construction prevents water migration and moisture accumulation. Because of the manner it must be applied, it provides excellent protection.

Advantages: The surface must first be prepared with primer. The price is greater because the product must be applied in layers: first, apply a coat of hot liquid rubber, then rapidly and firmly press the fabric reinforced sheet into that hot layer, and last, add a second coat of hot liquid rubber waterproofing. You may also need to apply two or three of these sheet layers, depending on the local building regulations. As a result, the elasticity is poor. Because it is hot, you must exercise extreme caution; it is preferable to have it administered by a trained professional.

  1. Membranes in sheets

Self-adhering rubberized asphalt membranes, which are made of rubberized asphalt bonded to a waterproof polyethylene film, are the most prevalent.

The greatest benefit is that they have a constant thickness since they are “pre-made” to a certain standard. Mechanically sturdy and hydrostatic pressure resistant. Even larger holes or damaged areas should be covered.

They may be used on a variety of surfaces, including concrete, metal, wood, and stone.4. Waterproofing using Cementitious Materials

Is a flexible waterproofing membrane made of cement. To enhance its longevity and efficacy, it may be made up of Portland cement, sand acrylic combination, plasticizer, and other active waterproofing chemicals.

Benefits: Simple to use; just mix the powder with water according to the manufacturer’s instructions and apply with a brush or trowel. Very accessible, since it may be purchased through masonry product suppliers or specialist dealers. Paintable. It’s also available in a number of colours. In most instances, one layer is adequate, but reinforcing mesh may be required in certain places. The price is low. Corrosion and weather resistance are built in. It may be used for both positive and negative waterproofing.
