How To Seal The Outside Of A House Foundation

If you are wondering how to seal outside house foundation there are several ways to get this accomplished. You can use Liquid rubber, polyurethane, or heavy duty drainage boards. All of these methods will help in preventing leaks and protect your house from water damage. In addition, you can use a rotary chipping hammer to remove the concrete around the crack. Once the crack has been cleaned, you can apply epoxy or urethane injection. These materials harden through a chemical reaction with water. Alternatively, you can use hydraulic cement as a temporary solution. However, this type of material will not fill in the crack completely.

Drain tile

If you are looking for a way to prevent water damage to your house, consider a Drain Tile Installation. This method involves installing a drain tile that is fitted into a trench around your home. It is then surrounded by soil and gravel. This keeps water from entering the basement. However, the installation process can be costly and may disrupt your landscaping.

Drain tile is a system of perforated pipes that collect and direct groundwater away from your foundation and basement walls. The system can be installed on the inside perimeter of your foundation or along the exterior as you build your house. The drain tile is usually made of PVC and has weep holes in it to reduce water pressure and the risk of seepage into the basement. Once the drainage pipes are in place, they are covered with gravel or a nylon filter sock.


Polyurethane is a plastic that can be used to seal the outside of a house foundation. It is flexible enough to expand to seal the outside of a foundation, unlike cured epoxy, which becomes rigid after being cured. While the polyurethane will never crack under normal conditions, minor foundation movement is likely to continue. In such a case, the only way to ensure a permanent repair is to use expanding polyurethane.

To make sure that your house foundation is secure, it is essential to check for cracks. Cracks larger than a quarter inch will need to be repaired. If the gap is larger than this, hiring a contractor will help you. This process will cost between $2,000 and $7,000, depending on the size of the foundation and the materials used.

Liquid rubber

Liquid rubber is a type of sealant that can be brushed onto a foundation or other surface to prevent moisture from entering the wall cavity. This environmentally-friendly product can be used on a wide range of surfaces including concrete, metal, and wood. To apply it, you should clean and dry the surface thoroughly. The best time to apply the sealant is when it’s warm outside (40F/5C). Allow it to cure for 24 to 48 hours.

Liquid rubber sealants are made with UV-resistant materials that are non-toxic and safe to use inside and outside a home. They are also tested for VOCs, emissions, water pollution, and performance. Although liquid rubber is an effective sealant for protecting the foundation of your house, other materials offer better protection.

Heavy duty drainage board

Waterproofing a house requires a waterproofing membrane that forms a continuous barrier around the foundation wall. A waterproof membrane will not only prevent water from entering the house, but it will also help preserve the structural integrity of the foundation wall. It is usually backed with insulating material or a heavy duty drainage board. Both types of coverings are attached to the foundation wall with clips, which are set into the wall prior to application of the waterproofing membrane.

The drainage pipe at the perimeter of a foundation wall should be wrapped in filter fabric or a free-draining granular material. This will keep fines from clogging the pipes. In addition, the drainage pipe should have a slope of 0.5% to 1.0%. This slope should be determined by the designer based on the site conditions and the overall water management system. He or she should also consider whether waterproofing or damping is needed.

Non-toxic coating

Using a non-toxic coating to seal your outside house foundation can help protect your house from potential deterioration. While some traditional coatings are highly toxic, many manufacturers have developed eco-friendly coatings that are safe to work with. These coatings can be applied by professionals or by do-it-yourselfers.

First, you should clean the foundation walls to remove loose dirt. If there are cracks, you may need to fix them before applying the tar coating. After cleaning and repairing cracks, apply the tar coating in a smooth, even stroke. The coating should extend one foot above the ground level. When the tar coating is dry, you can apply a latex primer to protect it from damage.
