Slurry Sealing

A slurry seal renews worn, faded or porous tar and seals it against water, adding years to a road or driveway for much less than a full resurfacing.

What a slurry seal is

Slurry is a thin mix of bitumen emulsion, fine aggregate, filler and water, spread over an existing asphalt surface. It fills fine cracks and surface voids, restores a uniform black finish and gives a slightly textured surface with good grip.

When to slurry seal

Slurry works best on tar that is still structurally sound but has become grey, rough or porous, with fine cracking. It is not a fix for potholes or failed base layers, so we repair those first. Sealing early, before water gets into the base, gives the longest life.

Roads, estates and parking lots

We slurry seal estate and complex roads, parking lots, school grounds and long driveways. Sections can be done in stages so traffic keeps moving.

Questions people ask

What is a slurry seal?

A slurry seal is a thin layer of bitumen emulsion, fine aggregate, filler and water spread over existing asphalt. It seals the surface against water, renews worn and faded tar, and extends the life of the road or driveway at a fraction of the cost of resurfacing.

How long does slurry seal last?

How long a slurry seal lasts depends on the traffic it carries, the condition of the asphalt underneath and the weather. Sealing a road or driveway before cracks and potholes set in gives the best results.
