From homeowners across Adelaide Hills.

“Three quotes, and Tierline was the only one that gave us a real by-the-face-metre price before they even came out, and the only one that put the drainage on the quote as its own line. The concrete-sleeper wall is dead straight along a sloping block, raked to follow the fall, and the number on the day matched the estimate.”

“Our old wall was bulging and over a metre, so it needed doing properly. Marco brought the engineer, sorted the council development approval and itemised exactly what the over-a-metre line cost instead of folding it into a round number. Signed off, certified, and no chasing the council ourselves.”

“A driveway sits above our wall, so it had to be core-filled besser on a proper footing. They sized the footing to the soil, named the reinforcement on the quote, and built the drainage in. You can see why the cheap quote that skipped all that was cheaper.”

“A low garden terrace under a metre, treated-pine sleepers posted into concrete and drained behind. They were straight with us that timber suited the height and budget, and did not try to sell us something taller than the job needed. Tidy work.”

“We wanted the look of stone to suit the heritage street, so they hand-laid a sandstone feature wall and priced it honestly against a block wall so we could see the gap. Drains by design and looks like it has always been there.”

“A winding garden terrace on a sloped block, so link-block was the right call for the curves. They set out the geogrid and the aggregate drainage the way the system is meant to be built, not just stacked blocks. Curves beautifully and has not shifted.”

“Rock-filled gabion across a wet slope at the back of the property. It drains straight through, which is exactly what we needed where water was always sitting. They managed the ground behind it with aggregate and an ag-line where it mattered.”

“Replaced a slumping railway-sleeper terrace with an engineered concrete-sleeper wall, drained the full length. Old wall and spoil carted away with the tip fees itemised, and the excavation on a tight block priced up front, never sprung on us at the end.”

“A tall wall holding a steep slope behind a new build. They handled the structural design, the certification and the development approval, gave us a realistic timeline up front, and built it to AS 4678. Worth every cent to have it signed off rather than guessed.”
