Storage water tanks

With time and use water tanks may develop leaks, especially as they are not normally constructed from a single piece. TECNOCOAT flexible systems allow interior waterproofing regardless of the type of material from which they are constructed or the liquid stored inside. (Check compatability in each case).

We have a certificate for contact with foodstuff and drinking water, the European certificate for protection of structural concrete (EN-1504) and the ETA certificate for 25 years of working life.

Construction or renovation of storage tanks

depósito de agua

The application of TECNOCOAT membrane provides perfect waterproofing and protection for storage tanks, both metal and stone, designed for practically all purposes (irrigation or drinking water, alcohol, chemical products, food storage etc.).

1. Tank support

The surface should be initially prepared.

tecnoband 100
Support and reinforcement band

A transversely deformable adhesive band, formed of a viscous-elastic layer coated on a nonwoven mesh. The nonwoven element allows adaptation to the support of the band and is highly recommended for specific applications of DESMOPOL liquid polyurethane and polyurea membrane.

Mastic PU masilla de poliuretano
Polyurethane mastic

MASTIC PU is a single component polyurethane mastic that cures rapidly on contact with atmospheric moisture, forming a hard sealant, elastic and of a medium-high elasticity modulus. For sealing of vertical and horizontal joints.

2. Primer

A primer resin will first be applied to ensure adhesion.

Primer PU-1000
Single component, solvent based, polyurethane resin as a primer

PRIMER PU-1000 is a single component, low viscosity, high solids content polyurethane resin. It has been specifically designed to increase bonding and improve the surface leveling of the substrates prior to the application of the DESMOPOL or TECNOCOAT.

Primer PU-1000
Two component, 100% solids, polyurethane resin as a primer

PRIMER PU-1050 is a two component, low viscosity 100% solid resin. It has been specifically designed to increase bonding and improve the surface leveling prior to pure polyurea TECNOCOAT system or the DESMOPOL application. It can be applied on porous substrates such as concrete or mortar

Primer PUc-1050
Two component, 100% solids polyurethane resin as a primer (for low temperatures)

PRIMER PUc-1050, is a two component, low viscosity, 100% solids polyurethane resin. It is specially designed to increase the adhesion of waterproofing systems, improve the rough floor in structural surfaces such as concrete or mortar, in waterproofing systems applications as TECNOCOAT pure polyurea or polyurethane DESMOPOL, and always in low ambient temperature conditions.

3. Waterproofing membrane

The TECNOCOAT membrane will then be applied directly over the primer. No additional finish coat will be required as TECNOCOAT holds a certificate for safe contact with both drinking water and alcohol.

100% pure polyurea membrane for waterproofing and coating

The 100% pure polyurea TECNOCOAT P-2049 system was developed as a two-component, sprayable, aromatic coating suitable for waterproofing, protection and sealing in general. It's made up of two high reactive liquid components, isocyanates and amines, which are mixed together using specific spray equipment, to form an aromatic, continuous, seamless, high density, solid and elastic pure polyurea membrane, with high mechanical and chemical resistance qualities.

It has CE marking on the basis of a statement made DoP Declaration of Performance (DoP) conforms to the UE 305/2011 regulation. The declaration is available on demand.

Tecnocoat P-2049 LV
Low viscosity polyurea membrane 100% pure for waterproofing and coating

The 100% pure polyurea TECNOCOAT P-2049 LV membrane was developed as a coating suitable for waterproofing, protection and sealing in general. The pure polyurea TECNOCOAT P-2049 LV membrane is made up of two high reactive liquid components, isocyanates and amines, which are mixed together using spray equipment (TC2049 http://spray-equipment.tecnopolgroup.com/), to form an aromatic, continuous, without joints, high density, solid and elastic pure polyurea, for protecting the polyurethane foam TECNOFOAM (SPF)

Stretchable polyurea membrane 100% pure for waterproofing and coating (>600%)

The 100% pure and elastic polyurea TECNOCOAT P-2049 EL system was developed as a single coating suitable for waterproofing, protection, and sealing, especially in elements with structural movements. The pure polyurea TECNOCOAT P-2049 EL membrane is made up of two high reactive liquid components, isocyanates, and amines, which are mixed together using spray equipment. TECNOCAOT P-204 EL is an aromatic high density and elastic pure polyurea and excellent elasticity.
