TECHNICAL EXCELLENCE & CAPABILITIES

Commercial-Grade Waterproofing Systems

Failed acrylic paints, cracked copings, and poorly tanked balconies permit rainwater to rot structural timbers and destroy ceiling boards. We build continuous hydrophobic envelopes that withstand Highveld hail and sun.

4mm Torch-On Bitumen Systems

Dual-layer elastomeric polymer-modified bitumen membrane heat-fused to primed concrete roofs with side laps fully welded and sealed with UV aluminum paint.

  • Polyester-reinforced non-woven matrix core
  • 100mm torch-welded hermetic side laps
  • Resistant to ponding rainwater & thermal shock

Parapet Wall Encapsulation

Overhauling cracked parapet copings, counter-flashings, and plaster joints using fiber-reinforced elastomeric waterproofing membranes and waterproof cappings.

  • Coping stone joint re-sealing & waterproofing
  • Stops wind-driven lateral moisture penetration
  • High-flexibility crack-bridging capability

Balcony Sub-Tile Tanking

Applying flexible 2-component polymer-modified cementitious tanking slurries beneath outdoor balcony tiles, including 150mm vertical perimeter wall upstands.

  • Guarantees zero water migration to lower rooms
  • Perimeter vertical wall upstand sealing
  • Compatible with all ceramic and porcelain adhesives

Box Gutter Relining

Seamless relining of concealed concrete or zinc box gutters using heavy fiberglass chopped strand mat and UV-stabilized polyurethane resin.

  • Seamless jointless lining prevents hidden leaks
  • Oversized rainwater sump & scupper retrofitting
  • Eliminates catastrophic internal ceiling flooding

Retaining Wall Tanking

Positive-side subterranean waterproofing on earth-retaining walls, incorporating dimpled drainage membranes, geotextile filters, and agricultural subsoil drains.

  • Hydrostatic soil pressure deflection
  • HDPE dimpled drainage protection sheet
  • Geotextile slotted French drain integration

Roof Penetration Flashings

Sealing complex roof penetrations around solar panel mounting stanchions, satellite masts, chimney bases, and plumbing vent pipes with custom flashings.

  • Heavy-gauge galvanized & lead counter-flashings
  • Solar bracket rubber dektite boot sealing
  • Highveld hail and storm resistant
PRIME BUILT SOLUTIONS STANDARDS

The 5-Point Quality & Workmanship Standard

Every waterproofing installation is executed with commercial-grade membranes, certified application methods, and uncompromising quality control across Pretoria East.

01

Dedicated Site Lead

Direct supervisory oversight on primer preparation, gas flame heat regulation, and lap welding.

4mm Certified Membranes

We never substitute thin 3mm or unreinforced felts. Only certified 4mm polyester-reinforced torch-on.

03

Daily Clean-Site Discipline

Old perished membranes, offcuts, and chemical drums are carted away daily from your premises.

04

Transparent Quotations

Itemised square meterage, lap detailing, and UV coatings clearly specified. Zero hidden costs.

05

Minimal Comebacks Standard

Correct preparation and full fusion ensure leak-free integrity through the heaviest summer downpours.

FREQUENTLY ASKED QUESTIONS

Waterproofing & Torch-On Insights

Key guidance on solving flat roof leaks, parapet saturation, and balcony moisture ingress.

Liquid paint-on acrylic waterproofing systems degrade rapidly under intense Highveld ultraviolet radiation and ponding water. Standing water softens acrylic emulsions, causing them to re-emulsify and blister. In addition, concrete slabs expand and contract thermally, tearing thin acrylic membranes. We install industrial-grade 4mm polyester-reinforced torch-on bitumen membranes heat-fused directly to primed concrete, coated with UV-reflective bituminous aluminum paint.
Balcony leaks occur when the sub-tile waterproofing layer was either omitted, punctured during tile adhesive application, or lacked adequate 150mm vertical upstand turn-ups along walls. Water seeps through porous grout joints, ponds beneath tiles, and finds structural fissures into the ceiling below. We strip the perimeter tiles, apply flexible polymer cementitious tanking, and install elastomeric polyurethane expansion joints.
Parapet walls are exposed to extreme sun and wind on both sides. Thermal movement causes cracks across coping joints and plaster capping. Rainwater saturates the porous brick core of the parapet and migrates downward beneath the roof trusses into interior ceilings. We encapsulate parapets with reinforced membrane systems and bituminous flashings.
To maximize the lifespan of a 4mm torch-on membrane (which can last 15 to 20 years), the protective bituminous silver aluminum UV reflective coating should be refreshed every 3 to 4 years to shield the bitumen from oxidation and Highveld solar radiation.
