APPLICATION / FUNCTION
Grout plastic and steel casings in monitor or water wells. Seal downhole instruments in test and observation holes. Seal cathodic protection installations.
ADVANTAGES NSF/ANSI Standard 60 certified. Low-permeability, flexible seal helps prevent commingling of aquifers and entry of surface contaminants. Does not contain any polymers. No heat of hydration, no damage to plastic casing due to temperature elevations.
RECOMMENDED TREATMENT
1. Pre-treat make-up water with Soda Ash to less than 100 mg/L total hardness.
2. Add one 50 lbs (22.7 kg) sack of AQUAGUARD grouting material into 14 gals (53 L) of circulating fresh water over a 20 - 30 second interval. The resulting slurry contains 30% active solids and has a slurry density of 10.1 lbs/gal, or 1.21 g/cm³.
3. Immediately tremie the grout into place after addition of AQUAGUARD grouting material.
Note: The slurry should contain suspended, unyielded bentonite granules which are allowed to hydrate and swell in situ.
