With more than 40 years of industry experience, Thorn Group delivers reliable waterproofing across South Africa for homes, apartment complexes, commercial buildings and industrial facilities. Our experienced teams provide professional waterproofing systems that protect buildings from moisture intrusion, leaks and long-term structural damage.

We use premium waterproofing products, including trusted Sika systems, for effective, long-lasting protection across a wide range of applications. Waterproofing often makes up a small portion of a construction or maintenance budget, yet poor installation remains one of the leading causes of expensive building defects. Our team ensures the correct diagnosis, product selection and application on every project, so that small line item doesn’t turn into a much bigger repair bill later.

Every property has its own waterproofing requirements. Thorn Group begins each project with a detailed inspection to identify the source of water ingress before recommending the right solution. Get in touch today to arrange a consultation and professional assessment.
