We Installed this septic system just before doing all the site work for the new residence at 221 Webster In.As soon as the site workwas finished it cut off access to get a tank truck or large excavator back to the septic tank location.After the foundation was poured it was brought to our attention that we made a mistake and the pump chamber was installed at 45 ft from the shoreline instead of 50 ft or greater. At this point in the project it is not possible to move or replace the pump chamber due to restricted access to the tank location and site layout. We are asking for a waiver to reduce the required distance from the shoreline and plan on coating the tank with the products listed and attached to the waiver form. I would be happy to provide some more pictures or info if required! Thankyou!

He is proposing to add the waterproof surface barrier to the inside of the tank and plans to use the same product that Sound Placement uses:TAMOSEAL+AKKRO-7T. I spoke with Keith at Sound Placement this morning and he said they typically coat the outside and bottom of the tank and if specially requested, they can also coat the inside of the tank, as long as the lid has not been secured to the top of the tank. He thinks coating the inside of the tank with the lid on is doable but would just require confined space training and a respirator so they don't often do it this way. I am wondering if this would meet the intent of the Class A waiver requirements, or if we should consider a Class C waiver. I was unable to find the Manual of Concrete Practice ACI 515.1 R available online for free. Everywhere I looked, it wanted me to create an account to download it. If you had a copy I could read through it, or if you have any insight or feedback you could provide, we would greatly appreciate it. Thank you.

Provide an absorptive surface on smooth precast or formed concrete by abrading the surface.Follow the surface preparation directions for the product in which AKKRO-7T is being used as an admixture. Mixing:Stir AKKRO-7T slowly and thoroughly using slow speed mixing equipment and a clean container. Do not aerate the AKKRO-7T. Recommended Mixtures: Bonding Slurry:Dry mix 1 part portland cement with 3 parts dry sand and add undiluted AKKRO-7T to produce a pourable slurry coat.Brush mixture thoroughly into voids and pores of surface to eliminate air pockets.Before slurry coat dries,follow immediately with patching materials that are compatible with portland cement. Patches, Overlays And Toppings:For depths 1/2 in(12.7 mm)or greater, mix 1 part AKKRO-7T with 3 parts potable water. Proportion dry sand, cement, aggregate and add measured amount of mixing liquid. Featheredging and repairs less than 1/2 in(12.7 mm) deep will require additional AKKRO-7T in the mix, Terrazzo: Make up a mixing liquid of 1 part AKKRO-7T to 3 parts potable water, Thin Coat Wall Applications: Manufactured wall coatings including TAMOSEAL, CONCRETE FINISHER, TAMMS SBC, and TAMMS STUCCO FINISH; mix 1 part AKKRO-7T to 3 parts potable water for mixing liquid, or as directed in instructions for mixing coating. Field Mixed Stucco: Mix 1 part AKKRO-7T to 3 parts potable water. Cement Plaster Coatings:Applications 3/8 in (9.5 mm)or less;use 1 part AKKRO-7T to 2 parts potable water.Applications over 3/8 in(9.5 mm); use a 1:3 mixture. Pointing Mortars: Manufactured tuckpointing mortars and other special mortars for thin applications: mix 1 part AKKRO- 7T to 3 parts potable water for mixing liquid. Application: Use only light pressure on trowel and finish with as few strokes as possible. Keep trowel clean and wet to prevent sticking. Do not over trowel. Mixes with AKKRO-7T do not normally require curing,but on hot,dry or windy days, it i5 advisable to cover with moist burlap for 24 hours or as recommended. Air-cure the surface for 2 to 4 days for normal use, and 4 to 7 days for heavy traffic areas. Refer to "PRECAUTIONS," for curing water containment structures. PRECAUTIONS/LIMITATIONS • Do not apply mixes modified with AKKRO-7Twhen the temperature is below,or expected to fall below 40°F(4 C)within 48 hours. • Do not use with air entrained cement-based products. • Do not use AKKRO-7T by itself as a bonding agent.It must be mixed with cement. • Excessive moisture and high humidity will slow curing time. • Provide adequate ventilation when using AKKRO-7T in enclosed tanks, reservoirs or other areas where air circulation is limited. • Air-cure cisterns,tanks or pools for minimum 7 to 10 days before filling with water. • Concrete mix designs using AKKRO-7T should be evaluated and tested for performance and application properties prior to use. • Store between 40 -F to 90°F(4°C to 32°C).Protect from freezing. • In all cases,consult the Safety Data Sheet before use.

DIRECTIONS FOR USE Surface Preparation:New concrete and masonry must be cured 7 days before application of TAMOSEAL.The surface must be structurally sound,clean and free of dirt, oil, and other contaminants. Abrade the surface to achieve a surface profile equal to CSP 1-3 in accordance with ICRI Guideline 310.2.Repair all surface defects including cracks and voids. Allow patches and other surface preparations to cure for 24 hours. Saturate surface dry(SSD)the substrate with potable water prior to TAMOSEAL application. Mixing:TAMOSEAL must be mechanically mixed using a slow speed motor and mixing blade to thoroughly disperse the ingredients. Do not aerate the mix. For Vertical Applications:One 50 lb(22.7 kg) bag of TAMOSEAL requires 2 gal (7.6 L)of mixing liquid.This consists of 2 qt(1.9 L)of AKKRO-7T blended with 6 qt(5.7 L)of potable water, or 2.3 qt (2.2 L)of FLEX-CON blended with 5.7 qt(5.4 L)of potable water.For Horizontal Applications: One 5016(22.7 kg) bag of TAMOSEAL requires 2 gal (7.6 L)of mixing liquid. This consists of 1 gallon (3.8 L)of AKKRO-7T blended with 1 gal (3.8 L)of potable water or 1.15 gallon(4.4 L) of FLEX-CON blended with 0.85 gallon(3.2 L)of potable water. Pour approximately one half of the required mixing liquid into an empty, clean container and begin slow speed mixing. Slowly add TAMOSEAL and the remainder of the mixing liquid as needed to the mixture.Stop mixing and allow the mixture to "fatten" for ten minutes. Re-mix to achieve proper consistency. Use mixed TAMOSEAL within one hour. Application:Saturate surface dry(SSD)the substrate with potable water before starting any TAMOSEAL application. Hand Brush:Apply TAMOSEAL using a 6 in.(15 cm)masonry brush. Load bristles with TAMOSEAL and apply a heavy coat using long, smooth horizontal strokes.Apply sufficient material to fill all voids. Final strokes should all be in one direction to produce an even texture and finish.Allow first coat to dry for 12 to 24 hours before applying a finish coat. Push Broom: Use a 5 gal (18.9 L)pail or wide mouth tub to hold TAMOSEAL. Dip a 10 in. (25 cm)tampico-bristle push broom into the TAMOSEAL and mix just enough to load the bristles. Apply a heavy coat using long, even horizontal strokes. Apply sufficient material to fill all voids. Lift the brush at the end of each stroke. Final strokes should all be in one direction to produce an even texture and finish.Do not overbrush. Allow first coat to dry for 12 to 24 hours before applying a finish coat. Spray: Use heavy-duty spray equipment capable of spraying cement coatings or mastics. Horizontal Applications:Use a water-based cure and seal from Euclid Chemical on all horizontal applications for added protection and ease of cleaning. Note:Prior to application, it is recommended that a mock up or field sample be made containing all materials that will be coated. Obtain approval of the architect or owner for the final color, texture and coverage rate before proceeding with work. Retain approved sample until the project is completed. PRECAUTIONS/LIMITATIONS • Do not apply to frozen or frost filled surfaces or when temperature is expected to fall below 40'F(4°C) in the 24 hour period following application. • Do not use on moderate to heavy traffic bearing surfaces. • When applied to the inside of open cisterns, tanks, etc., do not fill with water for at least 7 days after application. • Some colors may chalk or show water marks after weathering. • When using TAMOSEAL containing AKKRO-7T or FLEX-CON in enclosed tanks or reservoirs, make sure that adequate ventilation is available during the application and the total curing period. • Not recommended for negative side waterproofing where hydrostatic pressures exceed 8 ft(2.4 m)water head. • TAMOSEAL should not be applied to surfaces actively leaking. • In all cases, consult the Safety Data Sheet before use.
