1. Builders Sand vs Silica Sand?
Builders sand is soft and ideal for mortar and general construction, while silica sand is hard, high-purity, and used for concrete, glass, and industrial purposes.
2. How do I clean brick?
Use a stiff brush and water for general dirt, or a mild detergent for tougher stains; for moss or algae, a mix of water and white vinegar works well—avoid high-pressure washing on older bricks to prevent damage.
3. What drainage channel should I use for my patio?
For a patio, the drainage channel you choose depends on water volume, aesthetics, and material:
-
Plastic or polymer channels: Lightweight, easy to install, suitable for small to medium patios.
-
Concrete channels: Strong, durable, handle heavy runoff, ideal for large patios or driveways.
-
Metal channels (stainless steel or galvanised): Sleek look, corrosion-resistant, good for modern patios.
Tip: Choose a channel with a grate size and load rating suitable for foot traffic (and vehicles if needed) and ensure it’s connected to proper drainage to prevent pooling.
