CAVITY DRAIN MEMBRANE INSTALLATION IN BIRMINGHAM
Free site survey, a written diagnosis and a fixed, itemised quotation — for warehouses and factories across Birmingham
Serving warehouses, factories and commercial properties throughout West Midlands: basements and below-ground structures, surveyed, specified and put right with proven sump pump systems.
How the Work Is Carried Out
Industrial operators keep us on because we understand operational constraints. Works are scheduled around shifts, night and weekend working is normal, and fast-cure sump pump systems is used where the programme calls for it. Serving basements and below-ground structures across West Midlands, with ISO 9001, 14001 and 45001 certification behind the paperwork.

Why Choose MPS?
Cavity Drain Membrane Systems & Components
We install professional cavity drainage systems using high-performance membranes, channels, and sump pumps to control basement water ingress and dampness.
Studded Drainage Membrane
High-density polyethylene (HDPE) studded membranes create an air gap between damp walls and internal finishes, allowing moisture to drain to collection channels while keeping interiors dry.
Perimeter Drainage Channels
Continuous drainage channels installed at wall-floor junctions collect water from membrane systems, directing it to sump chambers for automatic pump removal.
Sump Pump Systems
Professional submersible sump pumps with battery backup and high-level alarms automatically remove collected water, protecting basements even during power outages.
Floor Membrane Installation
Cavity drain floor membranes with integrated drainage channels manage groundwater pressure beneath basement floors, preventing water rising through concrete slabs.
Membrane Plaster Systems
Breathable water-resistant plasters and boarding systems applied over cavity membranes create fully finished, habitable basement spaces with guaranteed dryness.
Condensation Control
Ventilation systems and dehumidification strategies integrated with cavity drainage to eliminate surface condensation and maintain healthy indoor air quality.
Cavity Drain Installation Process
Site Survey & Design
We assess basement condition, water source, floor levels, and drainage fall to design an effective cavity drainage system with optimal sump pump placement.
Channel & Sump Installation
Perimeter channels are installed at wall-floor junctions, sump chambers excavated and positioned, and discharge pipework connected to drainage systems or soakaways.
Membrane Application
Studded cavity drain membranes are fixed to walls and floors using approved plugs and mastics, creating continuous waterproof barriers with guaranteed drainage paths.
Finishing & Certification
Membranes are protected with plasterboard or render systems, sump pumps commissioned and tested, and full installation certificates provided with guarantees.
Frequently Asked Questions
How much does cavity drain installation cost?
Cavity drainage system costs vary based on basement size, ceiling height, number of walls treated, and sump pump requirements. Typical residential basement conversions range from £3,000-£8,000. We provide detailed quotes including all materials, labour, and guarantees.
What's the difference between cavity drainage and tanking?
Tanking creates a waterproof barrier that resists water pressure, requiring perfect seals. Cavity drainage manages water ingress by channelling it safely away, working with water pressure rather than against it. Cavity systems are more forgiving, easier to maintain, and better suited to below-ground applications with high water tables.
Do cavity drain systems need maintenance?
Minimal maintenance is required. We recommend annual sump pump testing, checking discharge pipes are clear, and ensuring drainage channels remain unobstructed. The membrane systems themselves are maintenance-free with 25+ year lifespans when properly installed.
Can you convert a damp basement to habitable space?
Yes, cavity drainage systems are specifically designed for basement conversions. When installed to BS 8102 standards with appropriate ventilation, they create fully dry, habitable spaces suitable for residential or commercial use with insurance-backed guarantees.
What happens if the sump pump fails?
We install sump pumps with battery backup systems that operate during power cuts, and high-level alarms that alert you to pump failure before flooding occurs. Dual pump systems are available for critical applications requiring maximum redundancy.

How we get to Birmingham
From our yard at Gamlingay in South Cambridgeshire, Birmingham is one and a half to two and a half hours. Day-return working on most jobs, so phasing is driven by your operations rather than by our travel.
We say this plainly because it shows up in the price. Mobilisation, access plant and preparation equipment are largely fixed costs, so a single small repair a long way from base carries a much higher rate per square metre than the same work next door to us, or the same work bundled with other defects on one visit. If you have more than one problem on the site, it is worth having them all surveyed at once.
