About Alisa Wilson

Setting up timber shuttering inside a muddy trench is not just a miserable way to spend a week…it’s also rife with setbacks. Pouring wet concrete in situ requires generous working room behind the wall stem, which is space that cramped urban boundaries simply don’t offer when you are building right against a boundary line. Specifying a factory-engineered precast concrete retaining wall shifts that structural work away from the mud and into factory bays where conditions are controlled and, ultimately, the end-result is far superior (not to mention easier to install). This vertical retention system sits practically flush against the property edge. Because the structural units are cast offsite to a high degree of precision, tolerances drop down, too. The resulting slim profile handles massive vertical earth surcharges without requiring a giant poured base that encroaches on the garden layout.
