A cavity wall is a type of wall that has a hollow space in the middle. It consists of two skins, which are separated by an empty gap or cavity. These skins are typically made up of masonry materials like brick or cinder blocks. Masonry is known to be porous and can absorb rainwater or humidity over time, leading to moisture buildup within the wall structure.
This can cause various problems such as dampness and mould growth if left untreated. Therefore, it’s essential to take necessary measures to prevent moisture from penetrating through the walls and causing damage to your property. Regular maintenance cheques and proper insulation installation can help keep your cavity walls dry and free from any potential issues caused by water infiltration.
The primary purpose of metal flashing is to divert water away from the cavity between two walls. This installation typically runs from the interior wall to the exterior wall, with a downward-curving weep hole that allows for proper drainage. The weep holes also create an airstream in the hollow space, which helps evaporated water escape to the outside. To prevent the rotting of wooden window frames, weep holes are installed above windows as well. It’s crucial for both walls forming this cavity to have an effective Damp Proof Course (DPC) and waterproofing coatings that ensure maximum structure impermeability. Regularly checking these elements guarantees there are no damages or issues present.
Transforming damp basements and subterranean spaces into dry, habitable areas is an economical and pleasurable way to expand a home or maximise existing space. One of the most effective methods for preventing moisture degradation over time is through constructing a damp-proofed cavity wall.
By damp proofing the cavity walls, water and moisture are prevented from passing through interior voids in walls and foundations. Continuous hollow walls serve as an efficient barrier that stops moisture from transferring from the exterior to the inner wall, thereby ensuring comprehensive protection against dampness.
This approach offers a long-lasting solution that enhances durability while providing homeowners with peace of mind knowing their property is safeguarded against potential damage caused by excess moisture infiltration.

Sussex Damp Treatments offers three types of structural waterproofing protection.
(Barrier Protection) is suitable for structures made of concrete or masonry that provide limited protection against water infiltration. This system involves applying a multi-coat waterproofing method to walls, floors and soffits with numerous interim layers to create a physical barrier that keeps the area dry. Construction joints, expansion joints and/or connexion joints are sealed using Hypalon Strips glued with an epoxy resin to enable high joint movement.
Structurally Integrated Protection is designed and built-in reinforced or pre-stressed concrete according to Eurocode 2, BS EN 8500 standards to minimise water penetration; BS 8102 or BS 8007 standards prevent water penetration depending on the grade of basement use.
Drained Protection uses structural concrete or masonry as a primary defence against water entering the structure. Any water that enters is channelled, collected, and discharged within the hollow created by adding an inner skin to the walls and floor. The system includes drainage systems and sump/pump units to remove groundwater from the structure using hollow drain membranes placed on walls/floors directing the water into channels leading it safely out of the building through proper drainage points. Traditional cementitious tanking systems are replaced by cavity drain membranes which allow pressure-free passage of moisture while controlling it in air gaps between membrane/structure preventing interior damage caused by dampness/moisture build-up.
