Good Morning Paul

Thank you for your question.

Once a Dryrod install has been completed and you wish to leave a plasterboard finish, we would advise using our Dryzone Express Re-plastering System. This 2 part system uses our Dryshield priming agent to help with existing moisture build up and our Drygrip Adhesive which will be your moisture and salt resistant adhesive to apply the boards to the wall.

If you have any further questions, please let us know

Kind regards

Good morning Charles,

Thank you for your question.

When applying this product to a wall with a cavity, we would advise an insertion is made from both the internal and external leaf to prevent any damage to the cavity.

Ideally cut the Dryrod in half and insert internally at the lowest mortar course and externally apply the Dryrod at the closest mortar course to 150mm from ground level. As normal these should be 120mm apart.

I hope this helps.

Kind regards,

Good afternoon David,

Thank you for your question.

For an internal application, the Dryrods should be inserted into the lowest accessible mortar course from your internal floor level.

You will need to remove all wall coatings prior to the application, this would include the skirting board and the existing damaged and salt contaminated plaster up to 1m above the proposed DPC line or 30 cm above the highest visible line of the rising damp in accordance with BS 6576.

I hope this helps.

Kind regards,

Good Morning

Thank you for your enquiry.

Holes can be left unplugged if you wish. We would advise the Dryrod has a 5mm recess and is not completely flush to the wall though.

If you have any further questions, please let us know

Kind regards

Hi James,

Thank you for your enquiry.

The Dryrods can be inserted from the external side of the wall. We advise when they are installed externally that they are inserted into the mortar course that is approximately 150mm above the external ground level.

I hope this helps.

Hi Andrew,

Thank you for your enquiry.

When treating walls thicker than the standard 9 inches, we would recommend using the Dryzone Damp Proofing Cream over the Dryrods as it is easier to instal for a few reasons:

To successfuly insert Dryrods into the hole, it is essential that the hole is clear of dust, dirt and debris. Whilst clearing the hole using the Dryzone Hole Clearing Tool is easy, clearing deeper holes, beyond the length of the Dryzone Hole Clearing Tool, can be challenging.

If the insertion hole is not clear of debris, then as you insert Dryrods they can create a small pellet of dust at their tip, or snag on dust and debris, which can prevent full insertion of the Dryrods and / or lead to contact between the end of the Dryrod and the face of the wall, potentially leading to visible dispersal of the chemicals on the face of the wall.

The grooves in the Dryrods are designed to reduce the potential for the above to take place, but will not necessarily prevent it if the insertion hole has not been cleared effectively.

Dryzone Damp Proofing Cream injection nozzles are narrower than the recommended 12mm insertion hole and so do not typically have this issue, and enable you to easily inject the Cream into the full depth of the hole.

I hope this helps.

Kind regards,

Hi Helen,

Thank you for reaching out with your enquiry.

On the assumption that you are referring to a cavity wall, we would recommend that you treat both the internal leaf and external leaf individually.

We advise this because you do not want to Dryrods to bridge the cavity in the wall and the rods would need to be inserted at different heights on both sides.

I hope this helps answer your question however if you would like some further information please feel free to get in touch with us on either 01403 210204 or via [email protected].

Kind regards,

Good Morning Christopher
Thank you for your question.
The Dryrods are designed for a standard 9 inch UK wall. If the wall in question is 12 inches thick then you would need to install a full rod followed by approximately a third of another rod into each drill hole
If you have any further questions please feel free to contact us directly on 01403 210204 or email us at [email protected].

The composition of black ash mortar — commonly used up until the 1920s — has varying amounts of sand in its composition.

As the active chemicals in Dryrod Damp-Proofing Rods require sand to be effective, the effectiveness of a Dryrod DPC in black ash mortar is variable. If you’re planning to install a remedial DPC in black ash mortar, please get in touch for personalised advice.

For internal installation: The "BS6576: Code of practice for diagnosis of rising damp in walls of buildings and installation of chemical damp-proof courses" recommends that treated walls should be left for as long as possible following DPC treatment in order to allow the wall to dry out as much as possible before replastering.

However, some replastering solutions are not an issue: Drybase Flex, Express System, Oldroyd Xp and Drybase Plaster Membrane are either barriers or not in direct contact with the Dryrod Damp-Proofing Rods.

For plaster based solutions like Dryzone Damp Resistant, Fast Set and Hi-Lime Plasters, it is recommended to wait 4-6 weeks to allow the liquid active to fully disperse and avoid any staining of the plaster.

Alternative solutions include:
A dab of Drybase Liquid DPM onto the ends of the rods to prevent the active chemicals spreading onto recently applied plaster.
Plugging the insertion hole with waterproofed mortar.
Plugging the insertion hole with Stormdry XR Mortar Mastic injected into the hole before repointing with mortar.

For external Installation (if the injection has been made externally): Effectively the same as above If using Dryzone DPC cream then DPC plugs can be fitted to the external drill holes.

Dryrod Damp-Proofing Rods can be inserted into stone, concrete or thermal / breeze blocks rather than the mortar course. You may choose to do this if the mortar course is too narrow to drill a 12mm hole into, or if the wall is concrete. The drilling centres will need to be reduced to 100mm instead of the usual 120mm spacing to account for the increased density in the substrate.

Yes, they can be. However, keep in mind that the chemical DPC should be created externally in the first mortar course at least 150mm above the external ground level.

Internally, the chemical DPC should be created in the lowest accessible mortar course above a solid floor, or in the lowest accessible mortar course below the timbers supporting a suspended timber floor. These are both typically lower than standard DPC height.

If the chemical DPC is created from the outside of the wall through to the inside of the wall, or vice versa, it is highly likely that the chemical DPC will be created at an incorrect height which may in turn compromise its performance.

The solution to this challenge may involve the creation of two separate DPCs at appropriate heights in a solid wall. Please contact our technical team for more information about your particular situation.

No, this is an invisible process. Assuming that the Dryrods have been installed correctly in accordance with our installation guidelines, there should be no signs that the remedial DPC has been formed.

Dryrods should be installed at a minimum temperature of 0°C and up.

It is important not to install them if the temperature is due to drop below 0°C in the next 57 days.

We do not recommend Dryrod Damp-Proofing Rods installation in wet frozen walls in cold temperatures as this can affect the dissipation of its active ingredient. It is preferential to wait until the temperatures have risen, the walls have warmed up, and any ice that may have formed in the wall has melted before using Dryrod Damp-Proofing Rods to create a chemical DPC.

Once the packet has been opened, any unused Dryrod Damp-Proofing Rods should be kept in the packet, and the packet itself should be kept in an airtight container or bag. Dryrod Damp-Proofing Rods should be used within 3 months once opened.
