Product information

Product name


Product description

Form-A-Drain is a foundation product that is intended for use as a concrete footing form and drainage tile. The product is manufactured from an extruded polyvinyl chloride (PVC) compound and is available in 100 mm (4 in.), 150 mm (6 in.), 200 mm (8 in.), and 250 mm (10 in.) depths. The 100-mm drainage channel (lineal) has a single hollow chamber, while the 150 mm, 200 mm, and 250 mm depths have intermediate webs to stiffen the channel.

The product’s system consists of 3.66 m (12 ft.) lineals that are slotted on the exterior face to allow for the entrance of ground water. The system also includes straight couplings, corner couplings, 45° fabricated fittings, 90° vertical “L” fittings, a snap-in adapter, single and double outlet fittings, spacer straps, and grade stakes to facilitate installation and accommodate drainage to the disposal system.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product must be laid on undisturbed or well-compacted soil so that the top of the product is below the bottom of the floor slab or the ground cover of the crawl space.
  • The top and sides of the product must be covered with not less than 150 mm of crushed stone or other coarse, clean granular material containing not more than 10% of material that will pass through a 4-mm sieve.
  • 250 mm (10 in.) specimens failed during testing after being impacted by a 1.0-kg tup (hammer head) dropped from a height of 1.0 m.  Careful attention must be considered during backfilling to limit impact so as to not cause damage to the product.
  • The product is susceptible to degradation by direct sunlight. Therefore, whenever Form-A-Drain is stored or installed outside, it is to be covered by an opaque material to prevent the degradation of the material by UV radiation until permanently covered.
  • This product has not been evaluated as part of a radon or other soil gas mitigation system. A higher level of performance may be required if the product is to be installed as a radon or other soil gas mitigation system.
  • Do not use filter fabric or any other geotextile membrane directly in contact with the product as it may prohibit drainage.
  • Drainage disposal of the product must be in accordance with Subsection 9.14.5., Drainage Disposal, of Division B of the NBC 2020.
  • The product must be stored, protected, and installed in accordance with the manufacturer’s specifications that are stated in NAPCO's Contractor Handbook, dated 2019. The handbook must be available at the job site at all times.
  • Based on the evidence provided, the product has been evaluated for applications up to depths of 3.7 m.

  Technical information

This evaluation is based on demonstrated conformance with the following criteria:

Evaluation requirements
Criteria number Criteria name
CCMC-TG-334613.04-20CCMC Technical Guide for Dual Footing Form and Drainage Tile System - extruded PVC

The evaluation holder has submitted technical documentation for the CCMC’s evaluation. Testing was conducted at laboratories recognized by the CCMC. The corresponding technical evidence for this product is summarized below.

Material requirements

Table 1. Results of testing the resistance properties of the product
Property Requirement Result
Impact resistance No evidence of cracks or fissures when tested for impact at the perforated and non-perforated specimen face (sides) or the solid wide edge (top). The 100 mm (4 in.), 150 mm (6 in.), and 200 mm (8 in.) specimens met the requirements. The 250 mm (10 in.) specimen met the requirements for both faces (sides), but did not meet the impact requirements for the solid wide edgeTable footnote (1) (top).
Resistance to soil pressure Max 20% deflection on smallest profile (100 mm) and largest profile (254 mm) Pass
Chemical resistance ± 2% maximum weight change The specimens met the requirements when exposed to 12 different potentially damaging chemicals. Results ranged from a weight change of 0.09% to 0.15%.

Performance requirements

Table 2. Results of testing the concrete form capacity of the product
Property Requirement Result
Stability The footing form and its accessories must remain within 10 mm of their original position after concrete placement and hardening. The product met the requirements. A maximum displacement of 4.72 mm was observed.
Concrete leakage No measurable leakage of concrete through the form. The product met the requirements. No leakage of concrete through the form was observed.
Load capacity The form must resist the anticipated loads imposed by the concrete placement. The product met the requirements. The product resisted the loads imposed by the placement of concrete.

Table 3. Results of testing the drainage capacity of the product
Property Requirement Result
Flow characteristics and perforation area Total perforated area per metre length > 30 cm2/m and perforation width (smallest dimension) 2.0 mm – 5.0 mm The product met the requirements for all product sizes.
