Advantages
- The main strength of this apparatus is that quantitative readings of leakage volume can be obtained.
- It is portable, can be easily carried out to the site
- When conducted using the same test parameters, the permanence readings for different walls can be compared.
- The water used in the test can be reused.
- Evaluate performance improvements made through repairs, by testing the same area before and after repairs are made
- Evaluate compatibility and prequalifying masonry units, mortar materials and mortar mix proportions.
- The improved spray nozzles used can give full square cone spray pattern i.e. the sprayed water can affect a wider area thus giving more accurate results compared to the usual spray pattern which only give flat spray pattern i.e. the sprayed water can only affect a small area.
