Renov Tix

Thixotropic, fiber-reinforced, high-strength repair mortar for the restoration of concrete structures

Drykos® Renov Tix is a single-component, thixotropic, fiber-reinforced, shrinkage-compensated structural cementitious mortar developed for the restoration and reconstruction of degraded concrete structures.
The product is formulated with high-strength cements, super-pozzolanic fillers, selected aggregates, and polymeric fibers, appropriately modified with modifying and stabilizing agents, capable of providing high mechanical performance, substrate adhesion, and long-term durability.
Thanks to its thixotropic rheology, Drykos® Renov Tix can also be applied vertically and overhead, ensuring excellent workability, absence of sagging, and thickness stability. After hardening, the product exhibits high compressive and flexural strength, excellent adhesion to concrete and reinforcement, high impermeability, and resistance to atmospheric agents, freeze-thaw cycles, and aggressive environments.

Substrate preparation

Substrates must be solid, clean, free from dust, oils, greases, loose or degraded parts. It is necessary to remove deteriorated concrete until sound and resistant substrate is reached. Surfaces must be adequately roughened by scarification, sandblasting, or high-pressure hydro-scarification to ensure high adhesion.
Oxidized reinforcement must be exposed and cleaned by brushing or sandblasting and appropriately treated by applying Drykos® Renov Steel.
Before application, the substrate must be saturated with water to the “saturated surface dry (SSD)” condition.

Product preparation

Drykos® Renov Tix is a single-component mortar to be mixed exclusively with clean water. Pour approximately 2/3 of the required mixing water into the mixing container, then gradually add the powder product under continuous agitation, avoiding lump formation. Subsequently, complete with the remaining amount of water until the desired consistency is achieved. The water/product ratio is approximately 16% by weight, about 4 liters per 25 kg bag. Do not exceed the recommended water quantity to avoid reductions in mechanical performance and product durability.
Mixing must be performed using a low-speed mechanical agitator (~ 300–500 rpm) for at least 3-5 minutes, until a homogeneous, plastic mixture free of agglomerates is obtained. If necessary, allow the mixture to rest for approximately 1-2 minutes and briefly remix before application.
It is recommended to prepare only the amount of product that can be applied within the workability time.

Application

Drykos® Renov Tix can be applied by trowel, spatula, float, or by spray with equipment suitable for thixotropic mortars. Application must be performed on a previously prepared, clean substrate brought to the saturated surface dry (SSD) condition. Before placement, it is recommended to remove any excess surface water.
The product must be applied by exerting adequate pressure on the substrate to promote penetration into the pores and ensure maximum adhesion, avoiding the formation of voids or discontinuities. In the presence of exposed reinforcement, ensure that the material completely encases the bars.
Application can be performed in one or more layers, depending on the required thickness. Thanks to its thixotropic consistency, Drykos® Renov Tix allows vertical and overhead applications without sagging, with indicative thicknesses from 7 to 40 mm per single layer. For greater thicknesses or in the presence of significant structural stresses, it is necessary to provide reinforcement bars appropriately anchored to the substrate to ensure stability and structural continuity of the intervention. Between one layer and the next, if necessary, it is recommended to apply the subsequent layer on a still-fresh substrate or, in case of hardening, after adequate surface preparation by roughening and moistening.
During application, avoid unfavorable environmental conditions such as strong solar radiation, intense wind, or high temperatures, which could cause rapid evaporation of the mixing water and compromise proper product curing.
At the end of placement, it is essential to protect the treated surfaces by wet curing, water misting, or equivalent systems for at least 24-48 hours to prevent plastic shrinkage phenomena and promote proper development of mechanical strengths.

Cleaning of tools

Clean tools with water immediately after use. Hardened product can only be removed mechanically.

Other indications
  • Do not apply on frozen substrates, during thawing, or at temperatures below +5°C or above +35°C
  • Avoid application in the presence of strong solar radiation, intense wind, or low relative humidity, conditions that can cause rapid evaporation of the mixing water and compromise final performance
  • Do not apply on inadequately prepared, loose surfaces contaminated by oils, greases, dust, or pre-existing treatments that may reduce adhesion
  • Do not exceed the mixing water beyond what is indicated to avoid reductions in mechanical strength, increased shrinkage, and decreased durability
  • For high thicknesses or structural applications, provide suitable reinforcement and anchoring systems to the substrate
  • Protect freshly applied surfaces from rain, frost, wind, and direct radiation for at least 24–48 hours
  • Adequately cure by moistening or protective systems to prevent plastic shrinkage cracking phenomena
  • Do not apply on non-absorbent substrates or water-saturated substrates with surface liquid film present
  • Use the product within the expected workability time; do not remix by adding water to product in the setting phase
