Northern Remedials is a leading basement conversion specialist, helping businesses and home owners alike to take full advantage of the space in their basements by the installation of robust waterproofing systems.

Utilising either cementitiuos renders (often referred to as 'tanking') or the installation of a cavity membrane system we can turn damp, water damaged or flooded basements into dry, usable areas that add value and make great financial sense.

Basement Conversion Methodology

We believe in thorough site investigation and full consultation with clients before the process of designing and installing an appropriate waterproofing solution can begin. With any cellar or basement below ground, there will always be the risk of water penetrating through the walls or floor. A basement refurbishment scheme cannot be considered before first making sure that you have control of both the current moisture within the building and also, the humidity and temperature.

We typically offer two waterproofing solutions dependent upon site conditions. It is not uncommon to combine the two systems for optimum results.

Cavity Membrane Systems

A semi-transparent, studded cavity drainage membrane manufactured from polypropylene which is applied to walls, floors and ceilings by means of special sealed fixing plugs. The membrane is relatively quick to install and can be covered with plaster board or a screed to enable decoration works to be undertaken. A sump and pump is fitted as part of the drainage system.

Cementitious Render Systems

A multi-coat waterproofing system composed of a waterproofing agent and cement-based powder which is mixed with water then applied to walls, floors, and ceilings by spray or trowel. It sets to form a bond with the masonry substrate, creating an impervious barrier to the movement of water.

Please get in touch with us to discuss your basement waterproofing requirements. We'll do all we can to help.

Combining all our specialist services, we can provide a complete structural repair solution from initial survey and investigation through to finished and fully refurbished load bearing elements.

Structural Repairs to Concrete

Utilising hand applied, sprayed and poured in place cementitious and resin based concrete repair materials, we are able to deal with concrete deterioration and cracking to restore structural integrity and protect against future problems.

Structural Repairs to Masonry

Our masonry repair services extend to include lintel replacement, the detection and replacement of wall ties, brick & mortar tinting and re-pointing operations. Please see our Masonry Repair page for more information.

Structural Waterproofing specialists in the North East, Northern Remedials are certified structural waterproofing contractors and have a wealth of experience in tackling damp buildings.

Rising Damp

The movement of moisture upward through permeable building materials by capillary action (through pores in masonry). Rising Damp can become a problem if moisture penetrates vulnerable materials or finishes, particularly in the occupied parts of a building.

The problem, which is most likely to affect older buildings where a dpc is not in place, and is caused when porous masonry comes into contact with damp earth. Damp masonry can result in a number of well documented structural timber problems such as wet rot, dry rot and woodworm. Rising Damp is unsightly, poses a health risk, and particularly damaging to internal decorations i.e. wallpaper.

The Solution: As always, the first step is to properly diagnose the problem. Once Rising Damp has been correctly identified as the source of dampness within a structure, the first step is to introduce a physical barrier using either damp-proof membranes or a chemical damp-proof course constituting hydrophobic (water-repellent) materials.

Contaminated plaster must be removed and replaced with specialist plasters that prevent the travel or residual salts and moisture from the masonry to newly applied surfaces and decorations.

Northern Remedials also specialise in basement waterproofing, full details of which can be found under the Basement Conversion section of this site.

Across the country there is an increasing incidence of wall tie failure especially for coastal areas, with high levels of atmospheric salt which accelerate wall tie corrosion.

Our masonry repair services cover the proper identification and replacement of wall ties together with ancillary services such as brick and mortar tinting, and general re-pointing operations.

Wall Ties

Metal ties which connect the outer and inner leaves of a cavity wall together to prevent bulging or bowing. Wall ties are usually 900mm apart horizontally and 450mm vertically, and composed of galvanised stainless steel.

Corrosion typically occurs because structures built before 1981 were constructed with ties with a zinc coating that was too thin to prevent deterioration, and with a life span of just 15 to 20 years there are now millions of properties at risk of serious structural damage.

As wall ties begin to corrode they can break leaving the inner and outer walls untied and at risk of collapse under high winds. More commonly, wall ties embedded in the outer leaf corrode and expand, causing cracking along bed joints extending upwards throughout the elevation.

The Solution: Using a metal detector and either an endoscope or the physical removal of bricks, we can effectively locate then examine the condition of your wall ties. Our investigation will also determine whether enough wall ties have been installed as part of the original construction and where they are missing we can specify replacement with appropriate high-grade units.

In instances of corrosion, we can cut out defective ties from the outer leaf and replace with new, robust wall ties that are guaranteed to last.
