SYSTEM GUIDE / BASEMENTS + BELOW GROUND

Start with the
direction of water pressure.

External and internal basement waterproofing are different engineering routes. The first intercepts water on the entry side; the second must remain bonded while pressure acts through the structure from behind.

TWO DIFFERENT ROUTES

Waterproof before entry—or resist pressure from behind.

Where the outside face is accessible, positive-side waterproofing protects the structure before backfilling. Where excavation is not feasible, internal treatment has to address active ingress, damaged backgrounds and counter-pressure as separate technical conditions.

01 / EXTERNAL

SCUDO SYSTEM®

A high-build trowel- or spray-applied route for counter-ground walls, foundations and concrete structures on the water-entry side, subject to correct substrate preparation and protection.

02 / ACTIVE WATER

BLOCKWATER

An ultra-rapid cement mortar used to stop local active water ingress before the wider waterproofing build-up is completed.

03 / BACKGROUND

WINPLASTER

A waterproof fibre-reinforced plaster used to rebuild and regularise suitable concrete or plaster backgrounds where a thicker treatment is required.

04 / COUNTER-PRESSURE

WINPOX CEMENT TIXO / WINFIX WET

Epoxy-cement routes for humid or moist cementitious substrates. Their roles differ and must be selected around pressure, finish and the following system.

INTERNAL REMEDIAL LOGIC

Stop, rebuild, control, then finish.

Internal waterproofing should follow the actual mechanism of water entry rather than a generic coating schedule.

  1. 01
    Map the water source

    Identify hydrostatic pressure, local active points, construction joints, cracks and wall-to-slab junctions.

  2. 02
    Stop active ingress

    Treat running water locally with the appropriate rapid water-stopping method before broader layers are installed.

  3. 03
    Rebuild the substrate

    Remove weak material and form a sound, continuous background with compatible repair or waterproof plaster.

  4. 04
    Select the pressure-control layer

    Choose the internal counter-pressure or damp-substrate route around the assessed structure and subsequent finish.

  5. 05
    Protect the completed system

    Coordinate penetrations, drainage, services, movement and later finishes so the waterproof layer is not compromised.

CHECK BEFORE SELECTION

Basement waterproofing starts before product selection.

01Which side is accessible?

External access usually offers a different risk profile from remedial waterproofing carried out only from inside.

02Is water under pressure?

Dampness, capillary moisture and hydrostatic pressure require different evidence and different design assumptions.

03Where are the joints?

Wall-to-slab junctions, cracks, penetrations and movement interfaces frequently control the success of the system.

04How will it be protected?

Backfilling, drainage layers, internal finishes and later fixings must not damage or bypass the waterproofing.

TECHNICAL DOCUMENTS

TDS and supporting files will be added to this website.

This guide explains the practical choices. The document library will be added as the controlled files are reviewed and organised by product.

TECHNICAL SCOPE NOTE

Basement design must account for the water table, hydrostatic pressure, structure, joints, drainage, external access and protection. Confirm the chosen system against the current manufacturer technical data.
