Waterproof Your Planter Box
All Planter Boxes need a Seamless Waterproofing Membrane to contain all the ponding/continuous moisture, bugs, bacteria and fertilisers found in the soil.
Our RTT - Waterproof Sealant is a scientifically engineered hybrid liquid rubber that has a unique resistance to protect against the above and can extend the life of your planter box up to 10 years or more.
