The advantages of the TECH-DRYAD block can be summarised as:
1. No water permeation through the block.
2. Dramatic reduction in efflorescence.
3. Resistance to biological growth as the block remains dry
(mould and moss etc.).
4. Higher 28 day compression strength.
5. Higher 28 day flexural strength.
6. Colour retention.
7. Properties close to natural stone can be produced.
8. The TECH-DRYAD block exhibits high resistance to salts as water
containing salt cannot enter.
9. Half the cost of liquid sealers.
10. Eliminates rising damp, therefore eliminating problems with applied
finishes delaminating at lower ground level.
11. Easier to wash down as dirt and grime doesn't penetrate into the block.
These blocks were placed in water for 24 hours, removed and broken in half.
After extensive research, development and testing, TASCO in conjunction with Tech-Dryad have succeeded in manufacturing a water repellent block. The TECH-DRYAD block is ideal for single leaf, parapet, retainer, basement walls and anywhere a water tight wall is required. A breakthrough in manufacturing technology means that the water repellancy is an integral part of the entire TECH-DRYAD block and not just a surface effect as with surface sealers. The active waterproofing material is blended throughout the entire block and will not break down or wash out over time. A mortar additive is supplied to create water repellent mortar joints to establish a totally water repellent wall. The TECH-DRYAD blocks may be painted over and rendered finishes may be applied.
