Structural Waterproofing

Structural Waterproofing

Structural waterproofing, also known as Barrier protection. The BS 8102:2022, is the protection of below ground structures against water ingress.

Increase your property value with the high prices placed on increased floor space in offices, shops, and residential uses. Within recent years its been made imperative that businesses and individuals maximise the use of all available space.

Basements are often overlooked, but they represent a valuable addition to your property. Once converted to a dry room, basements are suitable for everything from extra storage areas to offices and living accommodation and many other uses!
Cedarcare use various categories of waterproofing materials all of which are covered by current British Board of Agreement Certificates.

Type A Waterproofing

These are multi coat cementitious renders, screed, slurry coats and liquid applied membranes. Multi coat renders are modified with chemical additives. The modified mortar is applied by conventional rendering or screeding techniques in several layers. This method is used for waterproofing structures internally. Crystalline slurry coats are generally a pre-batched powder which when mixed with water will provide protection against water penetration through a structure. Crystalline technology reacts with free lime and moisture to substantially constricts the capillaries but still allow water vapour to pass. Slurry coats can be applied by brush or spray techniques. Liquid applied membranes can be applied as positive or negative side waterproofing to protect a structure from hydrostatic groundwater pressure and water vapour. Liquid membranes form a seamless fully bonded system which will provide adequate waterproofing to basements, decking podiums etc. It may also provide gas proofing capabilities.

Type C Waterproofing

Protection against water ingress into usable spaces by the incorporation of an internal water management system. This type of system creates a waterproofing solution by allowing groundwater to penetrate the structure as far as a cavity which is created between the external structural shell and a high-density polyethylene (HDPE) internal lining.

This is known as a Cavity Drained Membrane, which will allow groundwater into controlled drainage to a safe point of discharge. This is generally to an incorporated sump/pump chamber.

Rising Damp: The evidence of rising damp is usually found by the signs of a damp line appearing on the inside wall. The result of this rising damp is damage to interior plaster and wall coverings. It should also be noted that recent findings by the asthma foundation concluded that damp rooms can increase the risk of developing asthma.

Condensation Control: Many people associate the symptoms of black mould, dampness, musty smells and steaming windows with rising damp. However, they are quite often caused by the more common problem of condensation.
In Britain, condensation in houses is mainly a winter problem particularly where warm moist air is generated in living areas and then settles on the colder parts of the building.
