Foundation Waterproofing From Groundwater: Protection Methods For the Durability Of Your Home

Foundation waterproofing is a key stage in construction, affecting the durability and stability of any structure. Groundwater is one of the biggest threats to the foundation, causing corrosion, cracks and destruction. In this article, we will take a detailed look at effective foundation waterproofing methods, material selection and stages of work.

Why is foundation waterproofing important?

Protection against water penetration.

Groundwater rising through capillary effects can saturate the foundation with moisture, causing it to collapse.

Preservation of thermal insulation.

Moisture reduces the effectiveness of insulation, which can lead to increased costs for heating premises.

Preventing the development of fungus and mold.

Constant humidity creates a favorable environment for the formation of mold, which is harmful not only to the structure, but also to the health of the residents.

Extending the life of the building.

High-quality waterproofing helps avoid premature wear of the foundation and the associated repair costs.

Foundation waterproofing methods

1. Coating waterproofing

It is created by applying special mastics or polymer compositions that form a continuous waterproof layer.

Recommendation: Use polyurethane sealants such as Hyperdesmo , which provide elasticity and resistance to aggressive environments

2. Roll (membrane) waterproofing

It involves the use of roll materials that are glued or welded onto the surface of the foundation.

3. Penetrating waterproofing

It consists of special mixtures that penetrate the pores of the concrete, forming a crystalline structure that blocks the access of water.

4. Drainage system

Ensures drainage of groundwater from the foundation.

Stages of foundation waterproofing

Surface preparation

• Clean the foundation from dirt, dust and old coatings.

• Level the base, seal cracks and damage.

Applying waterproofing

Coating waterproofing: Apply the composition in several layers, allowing each to dry.

Roll membrane: Secure the membrane with a special adhesive or by the fusion method.

Installing the drainage system

• Dig trenches for laying drainage pipes.

• Backfill the pipes with gravel and wrap with geotextile to prevent clogging.

Protecting the waterproofing layer

To prevent mechanical damage, use geotextiles or protective panels.

Common mistakes when waterproofing a foundation

Insufficient surface cleaning.

This reduces the adhesion of waterproofing materials to concrete.

Wrong choice of materials.

Saving on quality materials leads to a short service life.

Lack of drainage.

Without a drainage system, waterproofing will not be able to fully protect the foundation from groundwater.

Ignoring seams and cracks.

If cracks are not sealed, water will find its way into the foundation.

Conclusion

Foundation waterproofing is an investment in the durability and safety of your home. Use quality materials, such as Hyperdesmo , and follow installation guidelines to ensure reliable protection against groundwater. Don't forget the importance of a drainage system to help avoid excessive stress on the foundation.
