Waterproofing is an essential consideration for people who are building a new basement which they intend to use for storage or inhabitable housing. Too often basement waterproofing is not given high enough priority, with the consequence of a cheap inappropriate waterproofing option being used to try and get inside an unrealistic budget. This often leads to failure and leads to loss which can be disastrous for the owner of the building or property.

Building a new basement is often well designed and built from well graded waterproof concrete blocks. A well designed and built structure will generally form the primary resistance to damp penetration as the concrete is too dense for water to pass through. However, you must always be aware that construction joints raise the risk of failure, even though the waterbeds and hydrophilic or hydrophobic strips are installed.

With this in mind, it is always a recommendation that with the structure itself a secondary form of basement waterproofing to be adopted, even though the structure is entirely new and built from waterproofing concrete. When the concrete construction itself is considered to be integrally waterproof this is described as type B form of waterproofing in the basement.

Where the structure is not considered to be integrally waterproofing there are two options for dealing with the potential for water ingress. One is to tank it and the other is to waterproof it with a Cavity Drain Membrane. Tanking a basement means that a product is applied on the inside or on the outside. This is designed to physically stop and hold back the water. It is referred to as Type A basement waterproofing treatment. A Cavity Drain Membrane system is applied to the inner face of the earth retaining makeup where it can allow the ingress of water depressurize it and direct it to a safe exit point. This is referred to as type C form of waterproofing of basements.

Tanking is a form of basement waterproofing to new structures. Whether you apply the mixture on the inside or on the outside of the structure tanking systems, you will need to be sure it is hundred percent defects free to be affective. Water is delivered under pressure against the structure. Most new build basement waterproofing benefits are designs which incorporate an exterior tanking system. It also includes a land drain for the purpose of draining the water surrounding ground areas and reduces the level of water which is delivered against the structure.

There are often many problems with land drains used in basement waterproofing. It is necessary that a land drain be placed on the outside of the structure below the level of the internal slab. This helps to relieve the quantity of water to the full depth of the retained soil. Many times the position of the land drain is shown on a drawing. Alternatively it is installed above the internal slab level and therefore could only ever be partially effective. These are well known forms and feasible remedial treatment that are common in this industry.
