Where space is at a premium, property owners look downwards to expand. At Peter Cox, our designs are engineered to achieve Grade 3 (Habitable) performance where the end use requires; the strict industry benchmark defined by BS 8102:2022 where no water penetration or dampness is permitted.

Peter Cox offers a comprehensive basement waterproofing design and installation service designed to meet British Standard 8102 standards, with a number of CSSW (Certificated Surveyor in Structural Waterproofing) qualified surveyors covering Edinburgh and Scotland. This is the essential benchmark for design liability and is frequently a mandatory requirement for third-party building warranties (e.g. NHBC).

Our dedicated waterproofing team can work with you at any stage of your project, whether it be at the start of the project with your architect or structural engineer when creating design plans, or beginning with a survey of an existing structure.

No matter the size of your project, whether it is a basement or cellar conversion, a new build project or structural waterproofing of commercial or historic property, we are here to help.

Basements are below ground structures, which means they can be particularly vulnerable to water ingress and dampness due to the region's varied soil conditions and high water table.

In order to prevent moisture entering the property and damaging furnishings, stored goods or decorations, waterproofing or tanking methods designed and installed to ensure long term usability and protect the structural integrity of the below ground space.

While some areas across the country are more susceptible to water ingress, especially in areas at risk of flooding or with a high water table, it's essential to choose a waterproofing system that offers full protection, and that it is installed correctly by trained professionals.

If you are considering converting your basement or cellar, qualified experts from Peter Cox are on hand to help you through every step of the way, from the initial design to installation.

The first step in converting a below ground space into habitable living is for a qualified CSSW surveyor to first inspect the area, and understand the requirements for waterproofing based on a risk assessment.

Peter Cox has a number of CSSW qualified surveyors covering Birmingham and the West MIdlands, who are on hand to provide expert advice and solutions.

They have extensive experience in dealing with moisture ingress in below ground structures, and will design a robust system designed to British Standard 8102 (BS:8102 2022 - Protection of below-ground structures against water ingress), the industry standard for below ground waterproofing.

They will then provide you with a survey report which will detail their observations, risks and recommendations for below ground waterproofing systems to BS 8102 standard.

They will be designed to fully protect from water ingress and will be made up of a combination of Type A (barrier protection) and Type C (cavity drained) waterproofing methods.

All installations that comply with BS8102 standard carry a 10-year guarantee - giving you long term protection and peace of mind.

Peter Cox are experts at carrying out basement tanking, often known as Type A waterproofing, across Birmingham and the West Midlands. Basement tanking is a method of structural waterproofing which can be used to prevent moisture ingress by using specialist products applied to walls and floors.

We can design a basement tanking system, or a combination of systems including tanking to meet BS 8102 standards.

Our locally trained technicians will then install the basement tanking system, taking care in order to create a continuous watertight seal.

If the wrong products are used, or installed incorrectly, this can lead to the tanking system failing and moisture ingress penetrating into the internal space, potentially causing water damage to furnishings and stored goods.

If the wrong products are used, or installed incorrectly, this can lead to the tanking system failing and moisture ingress penetrating into the internal space, potentially causing water damage to furnishings and stored goods.

Peter Cox rigorously follows waterproofing regulations as part of our commitment to best practice within our industry. You can be sure that any basement tanking carried out by Peter Cox will be of exceptional quality to the highest standards, keeping your below ground space dry long term.

Peter Cox are expert designers and installers of cavity drainage membrane systems cavity drainage systems, often known as Type C waterproofing.

These systems use a combination of high-density polyethylene (HDPE) membranes to create a managed cavity together with a series of hidden perimeter drainage channels to direct water to a sump pump station for safe discharge

The system acts as a total barrier to water vapour, protecting your internal finishes from dampness.This system can be used in conjunction with waterproof tanking to meet BS 8102 standards.

A cavity drainage system does not prevent moisture from entering, but immediately depressurises it and controls it away from the internal space.

In order for long term success, these systems must be designed correctly by a qualified professional, and installed and sealed with great care to prevent moisture, dampness and smells from penetrating into the internal space.

It is important to use a qualified CSSW professional to design this waterproofing system.

Inexperienced designers and installers can make mistakes that lead to extremely expensive remedial works being required and damage to stored goods and furnishings.

Peter Cox have CSSW qualified surveyors and trained technicians with vast experience installing these systems and keeping below ground spaces dry.

We have been installing basement waterproofing systems across Birmingham and the West Midlands for decades, often backed by long term guarantees when designed to BS 8102.

We can provide a number of expert waterproofing services to turn damp below ground spaces into habitable living space.
