- Model No. F-170 - Cementitious Water Infiltration Barrier



Sauereisen SewerSeal F-170 is a cementitious water infiltration barrier for use in wastewater collection systems. The product combines 100% calcium aluminate cement with finely graded inert aggregate, thereby offering notable corrosion resistance to mild acids and alkalies. SewerSeal commonly seals and resurfaces deteriorated masonry and concrete structures. Typical applications include manholes, wet wells, lift stations, and pump stations common to municipal wastewater. This product exhibits high strength to withstand loads imposed upon underground infrastructure.

Temperature of Working Area

Maintain a temperature of 50° - 90°F on air, substrate and material during mixing, application, and cure.

At temperatures below 65°F, the application becomes more difficult and curing is slower. Above 80°F, the working time decreases

Surface Preparation

The first step in any masonry rehabilitation is proper preparation of the substrate. For concrete substrates, refer to SSPC-SP13/NACE 6'Surface Preparation of Concrete' for detailed guidelines.

In order for any material to adhere, the substrate must be clean and free of all contaminants. Surfaces which are contaminated with oils or grease must be chemically cleaned of scarified to remove contaminants prior to beginning recommended surface preparation.

All chemicals, debris, and loose concrete must be removed. The recommended method of surface preparation is 5000 psi minimum hydroblasting or sandblasting. Hydoblasting should be utilized to remove laitance, contaminants or loose particles and to produce a clean hard surface. All standing surface water should be removed prior to applying the F-170. To ensure maximum adhesion and to prevent dehydration of the F-170 at substrate interface, the concrete should be thoroughly dampened with water prior to application.

Once the substrate has been properly prepared, active water leaks should be stopped with either Sauereisen InstaPlug F-180 or Hydroactive Polyurethane Grout F-370.

Where necessary, damaged areas should be rehabilitated prior to application of the F-170. To insure maximum adhesion and prevent dehydration of F-170 at the substrate interface, the concrete should be thoroughly dampened with water prior to application. If concrete cannot be dampened or an unusual stress condition exists, a concrete bonding agent is recommended. Consult Sauereisen for specific recommendations.


Mixing should be done mechanically with a slow-speed mortar mixer or drill motor with a 'Jiffy' type mixing blade to obtain a uniform consistency. The mixing equipment must be clean and free of contaminants. Batch size will be governed by the area to be covered, the number of workers applying the material, temperature of the area and the speed with which it can be placed.

Sauereisen recommends that powder and water ratios are accurately weighed prior to mixing. When water is measured in the field by volume, the approximate amount per 50-lb. bag of powder is in the range of 107 fluid ounces (3.3 quarts /3.16 liters) to 122 fluid ounces (3.8 quarts/3.61 liters).

Pour the entire amount of potable water into the mixing container and add the powder slowly, mixing continuously to avoid entrapped air. Mix slowly and thoroughly for 5 minutes until uniform consistency. Inadequate mixing or addition of more water will decrease physical properties and may cause cracking, excessive shrinkage and disbondment.


Sauereisen SewerSealTM  F-170 is usually applied by spincast methods within manholes. This allows application to proceed from ground level. In certain situations, applicators may choose to apply SewerSealTM F-170 by a straight shot spray method or by trowel.

Using a suitable material pump and spincaster nozzle with internal air motor or straight-shot nozzle, apply a uniform coat of SewerSealTM to the required thickness. The minimum thickness per coat is 1/2- inch.

For delivery of material to the spincaster, a pump will be utilized. Sauereisen recommends trailer-mounted pump rigs equipped with a 16-hp motor, mortar mixer and agitating feeder. These types of rigs may be sourced through the Putzmeister, RFI and ChemGrout Companies.

Sauereisen SewerSealTM  F-170 may also be used as a castable Polymer Concrete with the addition of five (5) pounds of 3/8 inch clean pea gravel per 50 pounds of SewerSeal powder.

Proper curing of F-170 is critical to the serviceability of the completed structure. F-170 has an initial set in 90 minutes at 70°F. A final set is achieved in 2 1/2 hours at 70°F, (ASTM C-403). F-170 may be topcoated with a SewerGardTM lining system after 8 hours at 70°F.

When mixed at the proper ratio of powder and water, a bag of F-170 will yield the following:
0.42 ft3 per 50 lb. bag -OR- 10 ft2 per bag at a thickness of 1/2-inch.

All equipment should be cleaned with a stiff brush and clean water at the end of each working period or when build up becomes pronounced.

F-170 is packaged in 50-lb. moisture-resistant bags on plastic-wrapped pallets.

Sauereisen SewerSealTM F-170 has a shelf life of six (6) months when stored in unopened, tightly sealed containers in a dry location at 70°F. If there is a doubt as to the quality of the materials, consult a Sauereisen representative.
