About Us
Specialist producers of Waterproofing Products
Our Dam Lining System is cost-effective, long lasting and easy to install. We have dams untouched in 26 years that still prevail beautifully. A value for money liner that can be easily installed and repaired (if necessary) via unskilled labour.
Our products have been in the market since the late 70’s and have been well established as excellent sealing compounds; initially branded as 'Viaseal' and now 'Waterblok' as Dalven was formed in 1997.
We are the sole South African distributors of Italian Casali torch-on rolls, which have been very well-received by the SA market and used extensively to waterproof buildings as well as line dams and reservoirs.
Our grafting paste and pruning compound are also of value to South African agriculture; whilst most other products apply to the waterproofing and roadworks industries.
We operate from our branches in Cape Town and Johannesburg and service the entire Southern African region as well as exports.
