Basement Tanking


Basement Tanking

Total Specialist Maintenance can provide a range of basement tanking systems for both internal and external tanking, recognised and authorised by the leading manufacturers.

We carry out full internal render systems to any underground structure to provide a watertight environment.

How basement waterproofing can help you

Our basement waterproofing systems can be installed on both new and existing structures. We can offer designers and property owners the most appropriate system to suit the structure using cementitious (render and slurries) and cavity drainage or external membranes.

BS8102 identifies 3 different types of use varying from Grade 1 suitable for plant rooms where slight seepage tolerable ie. Car parks; through to Grade 3 – dry environment: ventilated residential and commercial areas, i.e. restaurants. Note: Archives and landmark buildings require a controlled environment.


Barrier protection using either internal rigid cementitious (Sika-1 system, MC building chemicals Oxal DS-HS) or external membranes (self adhesive, pre-applied mechanically bonded, Bentonite sheet systems, coatings etc)


Integral construction using colloidal silicate pore-blocking admixtures cast within the concrete.


Drained protection using HDPE/polypropylene cavity drainage membranes (Safeguard, Sika, Newton).

What needs to be taken into consideration

We will also take into consideration the following factors in selecting the most cost-effective long-term remedy for basement waterproofing and basement tanking:

  • Age of building.
  • Intended use and life expectancy.
  • Locations and site topography i.e. Can water readily drain away?
  • Type and condition of structure i.e. unstable masonry may require strengthening/stabilising using gunite prior to waterproofing.
  • Availability of existing drainage.

Areas of expertise

Where water management is preferred we install drainage solutions and professionally fitted and managed pump waterproofing systems ensuring a long-term managed solution is provided to all clients.

  • Internal rendering of basements
  • Water management, internal basement tanking systems
  • External tanking systems
  • Remedial repairs to existing waterproofing

It prevents humidity from damaging the inside of your building because it shuts out water penetration. Waterproofing also ensures a building’s long life.

The number one reason that basement waterproofing is worth it for almost every homeowner/building owner is the reinforcement of the building’s foundation, and the addition of valuable space to the building.

Typically, extensive waterproofing measures are applied during construction to ensure that moisture is controlled at the initial stage. Waterproofing can also be done after a building has been built to solve problems as they arise.

Nothing will ruin a beautiful remodeling job like soaked carpets, moldy drywall and damaged furniture so it is essential that a basement be fully waterproofed before any finishing work begins.

In some construction projects, there is a need to apply waterproofing before the foundation concrete is cast. This approach is commonly needed in high water table environments in urban locations and on any structure where the owners are concerned about water infiltration through the foundation slab or confined walls.

Waterproofing is very important as it helps keep your house dry. It helps reduce humidity inside the house and thereby protects things inside your house from damage caused due to humidity or water exposure. It is also important for the veracity of the building.

Waterproofing a basement in the inside is a very popular option because it is done without major exterior excavation and, in some cases, can be done very quickly and economically.

The cheapest way to waterproof a basement is usually by installing an interior perimeter drain system/cavity drainage system or application of a internal waterproof render system.

Polyurethane liquid membranes and MMA and polyurea spray applied systems of waterproofing is used for the flat roofs, podium decks, bridge decks, balconies, and areas exposed to weathering. This waterproofing method is expensive however they are very quick to apply

Different Waterproofing Methods

  • Cement Based Waterproofing Method.
  • Liquid Waterproofing Membrane Method.
  • Bituminous Coating Waterproofing Method.
  • Bitumen Membrane Waterproofing Method.
  • Polyurethane Liquid Membrane Waterproofing
  • Polyurea hand and spray applied systems
  • MMA (Methyl Methacrylate) hand and spray applied systems
  • PVC membranes taped and welded systems
  • Bentonite waterproof membranes

Elastomeric coating is an above-grade exterior wall or roof coating that is approximately 10 times thicker than paint. It forms an incredibly thick yet flexible coating that helps waterproof the exterior of a structure.

  1. Wet and damp walls.
  2. Growth of mould and fungi.
  3. Rotting signs.
  4. Pooling water.
  5. Water leakage from the roof, ceiling, walls, joints and pipe penetrations

The most common type of warranty, used in waterproofing, is a Material and installation warranty. Typically ranging from 5-30 years, it’s a limited warranty that specifically covers the cost of materials in a waterproofing installation if those materials are proven to be defective, however insurance backed warranties can also be provided at additional cost which range from circa 5-15% of the contract value.
