Advanced Ground Solutions (Perth): what to know

Grounded in Advanced Ground Solutions's own published site. General information, not advice for your specific property.

A neutral look at what Advanced Ground Solutions publishes about itself: the four services it offers that overlap with this directory, who it says it serves, and what its own site does and does not say about cost.

"Advanced Ground Solutions" is the Perth company behind this directory's Kewdale, WA listing, and homeowners researching resin injection, restumping, concrete cancer repair or waterproofing in Perth come across it directly. This page pulls together what the company itself publishes across its site: who it says it is, how it describes each of the four services that overlap with this directory, who it says it serves, and what its own pages do and do not say about cost. Remedial Building Help does not provide or resell Advanced Ground Solutions's work; this is independent, informational content.

Who is Advanced Ground Solutions

Advanced Ground Solutions (AGS) is based in Kewdale, WA, and its own site states it "delivers engineered repair, stabilisation and foundation systems across Perth and WA." Its about page says the company "was founded on a simple idea: that every foundation problem deserves a permanent solution and not just a temporary fix," and describes selecting a method case by case depending on site conditions, among them "ground stabilisation with polyurethane or chemical grout," "underpinning," "stainless steel brick stitching," "concrete-free foundations with our Hexplates and ground screws," or "waterproof membrane application." Its homepage states, "For years, Advanced Ground Solutions has been helping Perth homeowners, builders and engineers protect their properties with permanent foundation and ground stabilisation systems," without giving a founding date or a count of completed jobs.

AGS names four groups it works with: homeowners, builders and contractors, engineers and consultants, and strata and property managers. For homeowners specifically, its site states, "We help homeowners protect the safety and value of their properties by repairing cracked walls, re-levelling floors and stabilising foundations," and it runs a dedicated "For Homeowners" page rather than treating residential work as an afterthought to strata or commercial jobs. That page states, "For most people, a home is the biggest investment they will ever make," and lists house underpinning, restumping, soil stabilisation, ground strengthening, excavation retention and concrete-free foundations among the "Residential Solutions" it provides. Its contact page does not state that any job type is excluded.

Resin injection: AGS's polyurethane slab lifting

AGS markets resin injection under the name "polyurethane slab lifting" (also called "polyurethane resin injection" on its underpinning page). Its process page describes it as: "Injected beneath the surface, this expanding polyurethane resin lifts and relevels slabs with precision, stabilising the ground and restoring confidence, without excavation, heavy machinery or long delays." The company sets out five steps: a site inspection, drilling "Tiny holes" into the slab or concrete ("no digging or mess required"), injecting the foam so it "flows into voids and expands, gently lifting the concrete back into place," the foam hardening to compress the surrounding soil, and a stated result that "the area is ready to use within hours."

For homeowners specifically, AGS lists driveways, paths and patios that have sunk or shifted, uneven pool surrounds, cracked or sloping garage floors, movement in slabs, and subsiding home extensions among what the method fixes. Used under a house footing rather than a standalone slab, its underpinning page describes the same resin this way: "it expands to compact the soil and gently lift sunken areas back into position," adding that "it requires minimal excavation and can often be completed in a single day with very little disruption." This is AGS's own description of its product, not an independent test result; for this site's own neutral, method-by-method comparison across the resin-injection, restumping and concrete-underpinning families, see underpinning methods explained.

Restumping: AGS's Hexplate system

AGS restumps (also called reblocking or re-levelling) using its own "Hexplate foundation system" in place of new concrete pads or stumps. Its restumping page describes Hexplates as "galvanised steel plates that spread load efficiently into the soil," installed instead of pouring new concrete or setting more stumps, and calls the result "a stable, concrete-free footing designed to last the lifetime of your home." The same page states Hexplates are "Installed in hours, not days," while its own FAQ on the same page gives a different figure for the full job: "Most projects can be completed in days, depending on the size of the house and access." Read together, those two statements describe the Hexplate installation step and the overall restumping project as different lengths of time, a distinction worth asking AGS to clarify for your own job rather than assuming either figure covers the whole process.

AGS's Hexplate system is a proprietary alternative to the traditional steel-pier or concrete-stump restumping covered elsewhere on this site; for unit rates and timelines drawn from published Australian cost guides for conventional restumping, see underpinning, resin injection and restumping compared.

Concrete cancer repair

AGS's concrete cancer page describes the mechanism in its own words: "Concrete cancer, also known as concrete spalling, happens when moisture gets into the concrete and reaches the steel reinforcement inside. The steel rusts, expands, and starts forcing the surrounding concrete apart." It names carbonation and chloride-induced deterioration as "the two most common causes of concrete cancer in Perth properties." Its listed warning signs are concrete that is flaking or bubbling, rust-coloured staining, cracks that are getting worse, and pieces of concrete breaking away. For the general mechanism and causes, see this site's own what is concrete cancer guide rather than relying on any one contractor's explanation.

AGS states it works on "balconies and elevated slabs" and says, "We have the equipment and expertise to operate safely at height." Its FAQ states the company serves "homeowners, property managers, strata managers, and commercial operators," with no stated exclusion for individual houses. Its repair process is described in three steps on the same page: you contact AGS and describe what you have noticed (photos help), an AGS specialist inspects the property and explains the cause, and the team then "complete[s] the work using the right materials and methods for your situation."

Waterproofing: AGS's polyurea membrane

AGS's waterproofing offer is a polyurea membrane system, described on its technology page as "Applied as a seamless, spray or injection-based system," forming "a tough, flexible barrier that protects structures from deterioration, corrosion and water ingress." For homeowners, the page lists basements, garages, planter boxes, retaining walls, and "Concrete slabs supporting extensions or renovations" among what it protects. On timing, AGS states, "Polyurea cures in hours, not days, meaning less downtime for your home or project site," and separately that "other trades can resume work the same day" in many cases. The company describes its own five-step process as a site inspection, surface preparation, spraying or rolling on the membrane, detailing corners and joints, and a final check once the membrane has cured.

What AGS says about cost

AGS does not publish a dollar figure for any of the four services on the pages checked for this profile: its restumping, concrete cancer, polyurethane injection and polyurea membrane pages, its homeowners page and its contact page. Its own FAQ on the homeowners page states, "Costs depend on the site and extent of movement. After an inspection, we provide a clear, tailored quote." Its concrete cancer FAQ similarly states, "That depends on the extent of the damage, where it is, and what repair method is needed," adding that "Smaller, early-stage repairs are often quite manageable." For the cost ranges this site has verified from other published Australian cost guides, see the underpinning cost guide; a written, itemised quote for your own property, after an inspection, is the only reliable number for any provider, including AGS.

Before you engage any provider

Whichever company you are considering, including Advanced Ground Solutions, confirm current licensing, insurance and a written, itemised scope directly with them before agreeing to work, and get an independent structural engineer's assessment first if the cause of movement or damage is not already established. AGS's own site states it provides "certified methods" and "certified engineering" without naming a specific licence number, accrediting body or trade licence, so these are worth asking for directly rather than assuming. See how to choose a remedial contractor for the questions worth asking, or our directory to compare quotes from other listed providers.
