Remedial works for homeowners

Leaking balconies, cracked driveways, crumbling render or a planter box that never quite dries out. We help homeowners understand what's happening beneath the surface and fix it properly.

Common scopes

What we're usually called out for.

Balcony and alfresco waterproofing failure, spalling concrete on driveways, carports and structural elements, cracked or crumbling render, planter box and wet area leaks, and crack injection where water is finding its way in. We also install decorative flake coatings for balconies, alfresco areas and garages.

Whatever the issue, our approach stays the same: diagnose it properly, explain it clearly, and deliver a repair that lasts.

Understanding the problem

Why homes leak and crack

Most of the problems we're called out for start small and get a little worse every winter. Knowing the real cause is what makes the repair last.

01

Balcony and alfresco leaks

Usually poor membrane application, a missing upturn where the floor meets the wall, or a drain that was never sealed to the membrane. Tiles and grout look waterproof, but they aren't.

02

Bathroom and wet area leaks

Wet areas leak at the junctions: where the floor meets the wall, around the shower hob and at the waste. A failed corner can soak a wall for years before anyone notices.

03

Cracks above windows and doors

In many older Perth homes, steel lintels above windows rust and expand, cracking the brickwork and render above them. Patching the crack without treating the lintel won't hold.

04

Spalling driveways and balconies

This is concrete cancer: the steel inside the slab is rusting and forcing the concrete apart. Closer to the coast, salt in the air speeds it up.

Worth checking

Signs to look out for

  • Water stains or bubbling paint on ceilings below a balcony or bathroom
  • White, chalky deposits on tiles, slab edges or walls (efflorescence)
  • Loose, cracked or tiles that sound hollow
  • Rust stains or cracks along concrete edges
  • Swollen skirting boards or a musty smell near a wet area

Caught early, most of these are a smaller and cheaper fix. Send us a few photos and we'll tell you what we think is going on.

What a waterproofing membrane is actually made of.

A lasting membrane is built in layers, each with a job to do.

12345
  1. Prepared substrateGround back, cleaned and repaired so the system bonds to sound concrete.
  2. PrimerSeals the surface and gives the membrane something to grip.
  3. ReinforcingBond breakers and reinforcing tape or fabric at corners, joints and drains, where movement and failures concentrate.
  4. Membrane, two coatsBuilt up to the specified thickness. One thin coat is where many cheap jobs fall short.
  5. FinishTiles on a bed, or a trafficable topcoat, protecting the membrane underneath.

A membrane is a system. Skip one layer and the rest can't make up for it.

The corner where most bathroom and balcony leaks start.

Floor to wall junctions take the most movement, so they need the most care.

COMMON FAULTRigid grout at thejunction cracksMembrane stopsat the floorWater tracks into the wall

The common fault. The floor and wall move slightly differently. Rigid grout cracks at the corner, and with no membrane up the wall, water runs straight into it.

DONE RIGHTMembrane turnedup the wallFlexible sealant,not groutBond breaker andreinforcing at the cornerCorner can move without leaking

Done right. The membrane turns up the wall, a bond breaker and reinforcing let the corner flex, and flexible sealant replaces grout at the joint.

How concrete cancer develops, and how we waterproof basements and walls from the inside, are explained on our services page.
